Title: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on March 22, 2016, 12:27:34 PM
It's time...........................for the MDRT transformer to be installed.

(http://i86.photobucket.com/albums/k114/themetalmartyr/2016-03-22%2019.04.22_1.jpg) (http://s86.photobucket.com/user/themetalmartyr/media/2016-03-22%2019.04.22_1.jpg.html)

Behold, goods direct from Belgium's finest witch dr of electronics (MJMP you will need to identify all those parts as I haven't a f**king clue what they are.....apart from the MDRT lol)

Before I make the mods I'll make some recordings.  I have recently fell in love with good old stock MP1 again and she's rocking like a mutha fucka now!

Watch this space!

Before I do this who did up the guides for MDRT replacement and noise Mod?

I think they could be improved and if I can collaborate with someone on this to make them better I think it would be a good thing.  I do documentation as part of my job and I'm used to making guides for idiots that details every step so I think I could improve the existing guides.

We can upgrade these together then?

I mean no offence but there are some things I think are written from an experts point of view.  As opposed to a guy who can just operate a soldering iron point of view..................like me?

Ok attached is a song using stock MP1 (pre MDRT)

patch is for rhythm

od1 7.5 od2 7.5 Master 5 Bass 2 Mid 2 Treble 2 Presence 6

Patch for Solo is

od1 7.5 od2 7.5 Master 5 Bass 4 Mid 2 Treble 2 Presence 6


No I know there a few little mistakes where one track on either side differs from the other, I could not be bothered to fix these because it still gives you an idea of the MP1 sound I get.

The solo is nearly there.  It's taken a lot of practice to get it close at that speed.  Funny I can do shit like that all day off the cuff and no problem, but when it comes to having a set piece suddenly it's more difficult!

See what you think.

Impulse I am using is Marshall1960B-K120s-SM57-Cap-0_5in               and that's a JBL speaker I believe.

Well once I begin  doing the mdrt upgrade I take photos.  Then add a bit of text to them detailing the step, then we'll blend the original together some of the new detail.  Sound like a plan stan?

If not I'll just document everything here with pictures for everything, I mean everything!  Then it's an MDRT "for dummies" guide.  I feel like starting the mod now since I have recorded what the stock one sounds like.

MJMP shall I do the MDRT first then the noise mod?  If I've asked this before forgive me  :'(


Thanks, I was thinking of horses at the time I wrote it lol

Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: MarshallJMP on March 23, 2016, 01:55:38 PM
Yep start with the MDRT,testing,next up the 3 big caps,testing then replace the resistor R9 and the 3 caps on the tubeboard (the high voltage ones),testing etc... if you do it in small steps and something goes wrong you know what you did last and it will be much easier to diagnose.The replacement of U4 creates the most problems so when you're up to that one just replace the opamp (socket) and test.
Best way to do it if you don't have a desoldering gun is cutting the pins like explained here

http://www.bustedgear.com/repair_IC_socket_install_2.htm
The use some desoldering braid to remove the solder from the holes.Tip;if the solder isn't sucked out entirely put some new solder on it and try again.

And if there are questions or doubts mail me!!!!! before you proceed.

Fantastic, I like that, steps!!  Clarity is a winner.  I shall do it just as you said.

btw the demo attached earlier is stock original Chinese tubes from uh probably 1989 or some shit like that lol

here is the same song played a few years ago.  We haven't played it since about then, but will be playing again soon as it's going on the album.

I think if I recall we showed up to that gig and they had f*ck all backline, and we're using combos lol  Sometimes it makes more sense to use combos in the size of clubs we play in.  I'm guilty of overkill lol.

Ok First few steps I shall complete with the MDRT upgrade.

Post by: rabidgerry on March 31, 2016, 02:56:55 AM
Started it last night.

Took out the old transformer (BTW anyone think it's worth trying to sell this on ebay????)

Cut the wire that was crimped, unsoldered the other from the power switch, unplugged the lo voltage plug and hi voltage plug to the tube board, out she came.

While I was at it, I changed the fuse holder as the one that was in there weirdly had no threads for the cap to screw on???  So I took that out and fitted a new one, soldered the wires accordingly.  I made a mess of the nut that fits this to the chasis what with clumsy turns of needle nose pliers, losing grip and trying to re grip etc but no one will see it anyways.  Eventually got round to getting the new one installed.  Mounted accordingly with the screws, soldered the blue wire to the power switch, and attached the brown wire (which had a crimp thing on it that I cut off) to the white wire that the previous crimp thing had been attached to.  I stripped the white wire a bit and brown wire from mdrt and soldered together, then heat shrinked the solder join for insulation.

Next step will be change the plug to either a UK 3 pin plug or an IEC male socket to fit in power conditioner.  Once tested this I can do the resistor change on the board that allows 240v as opposed to 190v.

Holy f*ck!

I tried MP1 with MDRT and no resistor on the tube board yet!  It seemed like a new beast.  Hard to explain.  It's like the MP1 has went to the gym and gotten a little leaner and more muscle mass.  It was built before but now it's gone Lou Ferrigno on my ass know what I'm saying?

What's the resistor to the tube board gonna do!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!  :whoohoo!:

Lou Ferrigno was the Hulk in the old tv series, he's pretty buff!  Still looks great these days, better than arnold schwarzenegger does that's for sure.  So an MDRT makes your MP1 turn into the hulk  :lol:

hey man I was joking too  :lol:  I wasn't offended or anything  :thumb-up:  This is why I said if you got MDRT you'd go the colours of your flag!  Don't you know MJMP turns Black yellow and red when he uses an MDRT loaded MP1  :banana-dance:  It's true!!  It's hard to tell between German users of MDRT and Belgium though, as they both go the same colour, so you need to pay attention to the direction of the stripes  :lol:

Of course I'm joking!

You liked the Hulk then Tomy?

Post by: tomy on April 03, 2016, 01:17:55 PM
I never thought you were offending. First time you talked about Lou
Ferrigno I know who he is : "the Incredible hulk " I remember his name because of the show but Although a friend of mine was Lou's fan, he wanted to body build just like Lou, but he was 4,5 feet tall.
So we used to called him "the incredible runt".

Well, first thing you've said about MDRT is : " it's gone Lou Ferrigno on my ass".I tried to figured out how it feels because I just ordered two of them  to MJ.

OH MY GOD!!   :lol:

Poor guy.  I'm not so tall myself so I know how he feels.


Well, first thing you've said about MDRT is : " it's gone Lou Ferrigno on my ass".I tried to figured out how it feels because I just ordered two of them  to MJ.

tWO OF THEM!!  Glad I got mine before they sold out then  :)

Ok this is just my crazy way of describing, I used Lou as he was/is a big strong guy, and for me I think the MDRT really makes MP1 sound like this, big and "strong sounding".  Perhaps I am deluded, MJMP, you know what I mean right?

I still have the resistor to do, I do this tonight.  Then once this is all set I shall do the noise mod.


I've ordered one as well and i'm glad you didn't say "it's gone Lou Ferrigno IN my ass"!  Not sure i want that effect.
Yes no "In ass"  jus "on ass" hahhaha  I'm glad I did not get that wrong when I typed it first otherwise there would be some raised eyebrows I'm sure.

Mike what way does your filthy mind work????    :facepalm:  tut tut tut  I bet it's Richards influence!!! >:D

Anyways buy MDRT'S!  (getting you some business MJMP).

Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on April 06, 2016, 03:22:29 AM
Ok got the resistor onto the tube board.  MJMP has instructed how to test the volts!!  I shall do this.

I accidentally tested it without doing the multimeter check before hand.  The sound is really different from before.  How I would describe it would be, it's got more cut through.  Or if you have ever used a guitar compressor that has and attack control?  Well if you  have you know this allows some of the peaks through untouched, retaining dynamics.  So while the compression is there you're still getting this 3D dynamic feeling.  So the whole sound of the unit has a new solid inner feel to the tone as opposed to a more "squidgy" sound (this is in reference to a high gain setting of 7.5 on both OD's).  So the squidgey sound is still there, that nice spongery responsive compressive feeling we all like, but through the middle of this sound we have like a solid harder feeling tone which is f**king awesome if I am to describe it appropriately.

No seriously man, it's great!  It's kinda hard to explain.  Still MP1 but more detail, more power, nice response, different feel.  I think more gain as well.  Also just for the record my MP1 is using the original stock tubes  :thumb-up:  So they're older than my girl friend probably lol

Hey Mike, well good news is MJMP said he's close to sending it all ( :whoohoo!: 2 x refurbished and MDRTed MB1s and a B500b), so now I need to buy a bass (or 2 or 3... :facepalm: ).

Hey RG how are you going with the new user guide for MDRT installation ?, I'm sure Mike and I will nut it out but it would be handy  :wave:

Actually, Mikes MP1 is sounding very nice with new tube board and noise mod (Mullard short plate + SPAX7, works well IMHO), so the MDRT upgrade will be very interesting. Also the hybrid patch arrangement is working well (so split mix after MP1 outs, mostly to TC GMaj (and using GMaj CC features but also mixing in a little (very little BTW) analogue MP1 signal). It has a tighter and tidier sound than I remember, but then we/you are using GCS 3 in the loop and most of our monitoring is via studio full range.
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on April 07, 2016, 05:57:26 AM
I have lots and lots of pics and It's probably going to be made in a manner that is way below your understanding, so If I explain that in a different way, it will probably be over simplified for you Richard, but hey I figured it may as well be made like a "for dummies guide" because the current one just skips things.  Like taking the tube board out.  It randomly just jumps to "and now fit this resistor, and you will have 3 possibly types of tube board, if yours is A do this, if yours is B do that, if yours is C do this".

So I took pics of literally every step or nearly, even trying to demonstrate what way certain leads should be disconnected and shit like that.  I had trouble working out how to remove the old tranny for example, because I didn't know what was connected to it and a few other small things that if detailed in a guide would make things run a lot smoother as opposed to having to bother MJMP will 5000000000000000 emails.

I am gonna write the guide up, give it to MJMP and then he can refine the what I say in case I get something wrong.

I will probably blend in the old guide and it's pics as they are still of use.

Hopefully it's useful to someone and I don't f*ck it up.

Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on April 07, 2016, 08:06:41 AM
Don't want to step on any toes but it's pruely as I have written guides in my job and I know how to make them more for the novice.  Sure this might be tedious for a more experienced person but sure if that is the case at least they can fly through it as opposed to a novice guy getting stuck a certain point because suddenly the tube board is out and available for soldering!

I'd feel proud if my guide was good enough to get used.

And all I can say is it's a worth while upgrade to buy an MDRT.

The guide for the noise mod is better however when I get round to doing it I'll take more pics and then myself and MJMP can update that too.

So currently I am at the stage where I have installed MDRT, and shit is good!   :poop:

I want to enjoy it now for a week before I start the noise mod.  If  play it at practice on Saturday and thoroughly get a stiffy over the sound then perhaps I will move on sooner to the noise mod, but generally I want to just keep the screws in place for a few days.

Well depending how much use the tubes have had over the years (and the original tubes lasted very well), some new bottles will sound killer.
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on April 08, 2016, 12:29:42 AM
call me insane but those stock bottles I have in there sound great to me.  It's nice to know there is a TAD model (I have one but cannot remember TAD001 may be) out there that is very very similar should anyone want to buy tubes quite like the original ones ADA put in in the factory.

Cool beans RG! MDRT is a must-have...
Now don't waste any more time and do the NoiseMod. Your positive impressions of the MDRT will definitely be consolidated. The higher quality/better spec filter caps in the PSU and the higher qual/better spec coupling caps on tne tube board will unveil the full potential of the MDRT'd MP1.
Same goes for the U4 replacement. The BurrBrown OPA2604 sounds (and then also "feels") way more "tube-like" than the standard TL072...and has a lower noise floor.
Keep em coming!!!

I've always said replace every electrolytic capacitor in any gear older than about a decade.
They do dry out, and though this is to variable degree, can easily affect performance.

I might drag it out longer now on purpose!!

ok three electrolytic caps installed!  Need MJMP's approval before I move on.  Had quite a job with one leg of one cap.  Where as I did the others in like record breaking time.  The very last cap was the quickest.  Why?  Because I didn't bother removing any solder and spending a long time trying to suck it all up to clear the holes for the new cap.  I simply reheated, removed the old while still warm.  Then reheated again, and poked the new caps legs through.  Whilst balancing the MP1 centrally with my chest (I was working with all this on the floor) and using right hand to solder and left hand to poke legs through.

One joint I'm worried about, and that's the f**ker that took so long.  Seems ok but I worry in case any solder is going onto a trace very close to it.  It's dirty a bit and I cannot see if there is any rouge solder.

Ok more tomorrow!  Can't do anymore tonight as the GF is getting angry and I need a drink, and something for my burnt thumbs.   :banana-trip:

Yeah I do need help!  I just don't get the time to do the whole thing in one evening.  I'm only going to get something small completed tonight.  Actually if I just do what I did with the last two caps (reheat the solder as opposed to remove all solder and re solder) then I will make quicker progress.

Thursday's aren't good for me, I can see me finishing it tomorrow evening instead.  I have some new Eminence CV-75's arriving tomorrow also so that may distract again  :facepalm:

Hi Richard,

Ok, so I worked this way; I screw in a piece of wood the rack vertically(now your hands are free to work on both side) , and use the light to get transparency, it makes easier where you unsold on backside (cause you can see the soldering iron through the main board), you unsold the whole list of caps, the manual really helps (thank you MJMP !). And when it's done, use a vacuum pump to clean every holes (the cleanest would be the better) Put the new caps on and solder on the backside, cut the tail of each caps. and it's done.

About the big capacitor in MP2 noise mod, it was the same way ... but those have 2 soldered points, pretty big ! So I did it that way :

left hand on the caps, (upper part of the board)
right hand with solder iron (on the other side)

soldering iron with highest power it can handle

With right hand you heat by alternating  between the 2 soldering points ; 2 seconds one... 2 seconds the other......etc until the 2 soldered points melt
While doing that, you try to make little circles with your left hand and pulling backward...  and softly the cap will be released

The most important is to work properly and ... easily ! that's why I've screwed the rack vertically

I think may be I'm not using enough heat?

MJMP reckons I may not be hence the difficulty sucking up the old solder.

I'm afraid of f**king up the pads as that's game over, well a pain in the balls at least.

I'll try a different tip on my iron and more heat.  I had about 2 thirds last night, or just over half way.

I eat anything except tripe and offal, so ravioli is good with me!

Hey RG, these EEV blogs are worth watching:
https://www.youtube.com/watch?v=J5Sb21qbpEQ
https://www.youtube.com/watch?v=fYz5nIHH0iY

The small chisel tip works well as the flat bit gets the heat in better/faster.  And a reasonably hot iron 360 c for soldering and 380 for desolder (is IIRC what MJMP uses).  I replaced the R913 resistor in one of my MP2s and managed to wreck a pad with the desoldering iron, I fixed it but it wasn't/isn't pretty  :facepalm: so now I'm very cautious about doing more...

I like Tomy's idea of mounting it vertically so you can get at both sides easily.
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on April 15, 2016, 12:55:31 AM
I basically did the mounting vertical, it wasn't really mounted I just kinda propped it up precariously, not ideal but hell I got my resistors in last night, the four in a row see attached.

Hey Richard, basically did watch a video on using some solder braid, this video in fact

https://www.youtube.com/watch?v=Fxu1LAoqTRA (https://www.youtube.com/watch?v=Fxu1LAoqTRA)

I bumped up the heat, and then applied this guy's technique to using the braid.  I wasn't trimming it and working from edge like this guy does.  However as soon as I started using from the edge, trimming a little and so on and so forth, I started winning.

I continued with the tip I had on my iron as MJMP said it was the best one to use.

I could continue tonight, but I may not be able to take photos which will be silly then since I am doing up the new guide and I have tried to take as many steps as possible, very, very comprehensive, may be overkill to the experienced but to the novice I guarantee it will be helpful.

Richard how did you fix the broken pad?  I nearly f*cked on my first MP1 doing the input mod.  I sold that unit on though  :lol: to some unsuspecting soul  :nono: because I dodn't think it sounded good either and I had just bouht the 3TMer and I think at the time I had a US model (the unit I'm modding at the mo) on the way from New York, so I flogged the 1st MP1.  I did the input mod well but I nearly wrecked a pad.

So far I've been doin good with the modding, only one kinda messy joint and even at that it's fine, MJMP checked it for me.
This experience will give me confidence to go on and start replacing electrolytic caps in other units, perhaps I could do my Rockman Sustainor by myself?

Hey Tomy (and Peter), I'm about to become a bass player (well sort of, I need to buy a bass LoL), I've got 2 MB1s (with MDRTs' and MJMP ravioli cumming soon  :whoohoo!: ) and a B500b albeit a US voltage amp and Mike gets his MDRT  :whoohoo!: , comments to come when it's installed.

Hey RG, yeah broken pad  :facepalm: (F^&&%%^$%$k), so in this particular instance, I was lucky as I could use a combination of a fair bit of solder and a bit of wire to make it all connect (MP2 R913). It wasn't pretty, and I'm not super happy about it, but it works fine.

So to break it down a bit, while I was using my desoldering iron on one side of R913, I suspect I've overheated it. The pad lifted off (and then disappeared into the ether).. not good  :facepalm: . So fortuitously it wasn't a particularly complicated connection, so I managed to bridge the broken track (as now no pad) and splash some solder to where it needed to connect to and "bobs your uncle" it worked all good but I'm pissed that I f&&&cked up.. Although it was my first go at a real MP2 (I'd practiced a bit on dead bits of gear).

Now MJMP please feel free to interject here but the less time you have to spend on a solder join the better. So to that end you need your iron at the right temp which is up there (360c solder/380c desolder) and like microwave ovens I'm sure it varies a bit.... ). Basically you want to spend the "least" time at a particular joint (so pads don't lift etc) (think heat and time are different with different results). So a "hot" iron makes sense (careful but does pay off if you are careful  :thumb-up: ) Crap here's me crapping on about soldering, this is MJMP's area...

The other thing I'd say is that from what I've gleaned, generally you'd suck the solder out (desolder station or solder wick stuff), the part will drop out (or easy to pull out), nice clean hole, then solder in the new part.. Now if you do what you have done (heat the joins and pull the part), yeah it works (with burnt fingers typically)) but I suspect the MJMPs' of this world don't do it that way.
Anyway my 2 cents worth...
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: Systematic Chaos on April 15, 2016, 10:08:52 AM
I have set my soldering station to 400°C, both desoldering and soldering.
When desoldering, I heat the solder joint just to the moment the it gets liquid and immediately push the button on the solder-sucker.
I tried desoldering braid but I personally get way better and cleaner results with the method mentioned above.
Up till now, I have yet to have any lifted traces or other nightmares.
Just make sure to just apply the soldering iron tip to the chunk of solder and don´t try to poke around into the solder joints. Immense heat + pressure + prying around = no good!  :nono: :nono: :nono:

Hey RG, well Peter can introduce himself, Peter H Bower, he's probably our most experienced MB1 user.
Yeah a sort scale will be easier to play but the long scales sound better (from my experience), but a Squire Jaguar would probably work for me (at the cheap end)
Sorry Godzilla, I did my best LoL.

I'm a bit with SC here (hey not that I'm a soldering expert, patching sure no worries :thumb-up: bring it on...) but the higher temps (and 2mm chisel tips) get it done quickly (obviously line up your ducks first). I'm all for lead solder, the lead free adds complications, I can't say I hate it (as I haven't used it) but I take MJMPs advice on this one. I just checked my iron temp, I've got it at 350c for soldering leads, which works well and is quick so if that's as high as your iron can go I'd proffer it's quite usable.

Wow, the ravioli club, cool I like ravioli  :thumb-up: and thanks Tomy, when the MB1s arrive I'll certainly lean on you're experience  >:D .  Upside is I have a 5 string Musicman sub that lives at my place, now that's not a bad start. Moreover it's just had new strings delivered  :whoohoo!: which I'll no doubt put on and set up  >:D though my bass player may want to attempt this himself.

I'm thinking I'd like an Alembic but lets see where it goes. I'd love to get back the bass I made (way back when) for a friend, straight thru neck sugar maple, Maton EB4 body shape, maple wings, ebony FB, 33" custom scale (out with the protractor etc), Fender Jazz neck dimensions, nice bass.

Thanks RG.  Alembics are really nice basses but also come with a big price tag.  Short scale basses are fine, but the longer scale basses generally sound better and are easier to tune. Although for guitarist like you and I, the shorter scales are easier to play.

I have heard this about them but I've never thought my bass sounded any different.  Apparently shortscales can be quite lacking in treble and have a flabby low end.

But then I can only speak for my Cort and I think it sounds great.  Only complaint is the treble strings always seems really loud to me and "stick out" a lot more compared to the low E.  Have f*cked about with pickup height till my hearts content and still never seemed satisfied.

But anyways, will get the Op amp in today and the rest of the components for the noise mod.

Hey RG, take your time, don't burn your fingers LoL.  I don't hear much about Alembics these days, I think they start at $14k, they are seriously nice basses.  They (well they used to) put all the wood bits for a new guitar together for a year just so the wood bits can get to know one another.

As you increase the scale length the bass response improves and are less flabby (more tension in the string) IIRC Peter has some 36" or longer basses. But for us guitar types, they get harder to play. I was reasonably impressed with our bass players Squire Jag, it set up quite well (I did the set up) and isn't too hard to play being a short scale (though getting a hard case for them is tricky).

So diode in and unit tested.

here is what I said to MJMP

Quote
Right tested.

No weird noises.  I'm not gonna lie, didn't notice anything major in noise loss.  Personnally didn't think it was noisey to begin with.

What I did notice, straight away was the patch that I had initially set before I started modding was at 7.5 on each OD.  The OD1 clipping light was lighting up occasionally as it should.  Where as as soon as I put in MDRT is overloading like crazy, and now after the test for noise mod, it's lighting up even more so, so I shall have to adjust it.

Other things I noticed, it sounds mega touch sensitive, but this could be because the gain trim pot needs adjusted.  It feels really compressed.  The OD1 seems to distort completely different to the way it did before.  And it just generally sounds different.  I liked it before, now it's like a steroid using body builder.

What will modding the tube board do since these are the true final steps?

I am pleased I've done this mod, but I probably will need to reprogram and get the "Gerry" sounds.  Currently it's oozing "I think I'm a marshall, I think I'm a marshall" type tones lol

Perhaps with the trim pot adjusted I'll noticed it being quieter.

What does replacing the caps on the tube board do for the sound?

Replacing the caps on the tube board reduces noise even more.
The tube board is where lots of signal passes through...higher rated/higher qual caps help reduce noise.

For the Od1 adjustment fire away with some heavy palm muted E5 chords (Pull me under, Master of Puppets,....) until the clip just lights up occasionally

Yup SC, I'm familiar with the trim pot adjustment, and I do similar sort of playing to reach what I think are the loudest sound that can be made with my guitar.  Another thing I do is pinch harmonics repeatedly on the low e string.  That's another good one.

Cool, perhaps get a look into the caps replacement at the weekend. Am very busy at the mo

This is not just a noise mod but also a "tone" mod bringing back the original tone and then some more.

If the gain went up and the noise level is the same then the overall noise level has dropped compared to the gain you had before.If you lower the OD1 trimpot to the same gain you had when it was before the mod you will have have less noise.

A teacher once said to me,"a good amp starts with a good power supply".If the supply is crap so will be the amp.So a good transformer and high quality caps will do the trick.Why do you think those old marshall heads sound so good.Big transformer,big quality caps and a good choke.If i compare my JCM2000 with my marshall plexi you see a hughe difference in the transformers,the 2000 has less caps and no choke.

https://www.youtube.com/watch?v=9GDY4mYSp9s  Here is a YT clip a marshall 68 plexi,no pedals just an LP straight into the amp.

My mp-1 has all elektrolytic caps replaced.Problem is it's about 60 caps you need to replace.But the sound is much better.

SC explained that to me couple days ago... he put metal oxyde caps inside an amp. He replaced all the caps...
Lot of work but, according to him, it paid : better tone, less noise.

Not to mix up things.... It´s metal oxide resistors I personally prefer.
Cap wise, you can´t go wrong with the Panasonic Gold Caps I got from MJMP for my MP-1 tube board back in 2009.
I addition, I always go with either Orange Drop 716P film/foil or WIMA film/foil caps.
Large Filter Caps of preference are TAD (F&T) Gold Caps.
For the real small values it´s Silver Mica.

I agree with SC except for the metal oxide resistor.I use them also but only where i need a higher power resistor.For the rest it's metal film for me.Why you might ask,well a few reasons,first noise,metal oxide resistor generate more noise and the temperature coefficient is worse then metal film resistors.Metal film resistors also have a higher long term stability.

Soundwise there is no difference.

My mp-1 has all elektrolytic caps replaced.Problem is it's about 60 caps you need to replace.But the sound is much better.

 :facepalm: Sorry I should have mentioned that I realise the noise floor will have dropped since the OD1 is now clipping too much and will need adjusted. 

Oh well I sorta mention it in the email text that trim will need adjusted, that's what I was alluding to if you get me.

Is it normal for OD1 to need adjusted after these mods?

Right so this mod is a tone mod not just a noise floor mod?  Ahhh Ok, well it makes sense as it's different.  Kinda Fresher and fitter version of what is was before.

And then there is the MDRT also contributing to things as well I'm sure.

Also I am familiar with the thinking that replacing the caps will help shit.  Remember back to me talking about getting my Rockman Sustainor recapped?  Well perhaps I could recap this now as well.

In fact I have many units I'm sure could recap.  Ever since I bought all this old shit!

Ok what exactly are the electrolytic caps for and how do the affect the sound?  I realise they die after about ten years or so, or should I say dry out. EDIT: oops MJMP has just answered this two posts up

MJMP could you alter your JCM2000 then?  Or have you done so already.
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: MarshallJMP on April 21, 2016, 02:30:43 PM
Yes the OD1 gain can change due to the D16 diode.

A recap is always good to do.

Nope ,i'll never get a plexi sound out of the 2000.It's not a bad amp but it doesn't have the wauw factor.

Ok Ok Ok, lets go off topic again lol

Right so if JCM 2000 can't do a plexi, what is it good for?  Even better question, when it came out, was it supposed to deliver "Plexi" tones?  Just curious.  I suppose it can't be faulted if the amp wasn't designed to have that ability to recreate certain tones.

BTW  Is there anything on here I can read or perhaps you guys can fill me in, on what the design and goals where off the ADA MP1.  Ok So I know it is Marshall voiced correct?  Is it meant to sound like a JCM800 hot rodded?  You know that kind of stuff.

Can you get a "plexi" tone with an MP1?  Just curious about these sort of things, not that any of it will affect me or my requirements.

Long shot....with some eq tweaking. Tube Clean with ODs more or less maxed and some added tube poweramp saturation/distortion

Post by: MarshallJMP on April 22, 2016, 03:40:51 AM
Yes the MP-1 is marshall voiced in a way.But it doesn't "nail" the 800 sound.But it's close.The 3TM does nail a 800 hot rodded sound better IMO.

The 2000 was more designed to be a hot rodded 800 but it doesn't sound as good as a 800.

The plexi sound is almost impossible to get out of a preamp because it's a 50/50% sound,50% preamp distortion,50% power amp distortion.And with a preamp you don't have that power amp distortion.Even if you use a tube power amp.Now you have to set a plexi ridiculously loud to get that sound.
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: rabidgerry on April 22, 2016, 04:41:32 AM
Ok so MP1 doesn't nail an 800, so what does it do?  What did people use it for?  Does it have as much distortion?  Like what were they trying to achieve?  Why was it popular?

To me accuracy in nailing certain amp tones isn't required so none of this matters to me, but I am curious, just interested in the story.  If a piece of gear has something unique about it and doesn't quite copy something else then that's a bonus in my tonal goals, it means it has it's own unique flavour, I hope you guys understand me?

MP1 for me sounds nothing like 3TM so if a 3TM does hot rodded 800 well then I'm just assuming the MP1 falls short by quite a bit.  To me the 3TM sounds a lot more modern, than an old JCM800 hot rodded, but I'm sure you can get that out of it also, you guys are the experts not me.

Although I will say now that my newly modded MP1 feels like it has enough distortion for me.  However I will for variety make patches with less distortion on the unit so I can hit a boost.  Different distorted tone textures is cool by me, so achieving sounds using slightly different methods is valid.  I still have to use an EQ in front of MP1.  Not tried that yet.

Now back in the day 99.9% of the LA Hair and Glam scene was pairing their 2203/JCM800 with some OD or Dist pedal or other to get a more focused and higher gain.
The (original) MP-1 took that and transformed this refined (pre-)amp sound in a preamp circuitry, add MIDI, one Solid State and 2 Tube/IC channels, an FX Loop and a Chorus.
In my book the MP-1 is "The" hot-rodded JCM800 of the late 80s/early 90s.

Now the 3TM takes that initial vibe and moves it one step (or better 2 Triodes  8) ) further. If I were tempted to give a comparison: Marshall 2555 Silver Jubilee on maximum steroids

If you wanna go a tad bit more to the traditional Marshall sound/vibe I´d say Mod1 (cathode follower).

For a more modern (think DSL/TSL/sorta JVM) Marshall sound the Mod4MkII does the trick.

That leaves Mod3.1 and 3.666 ....
Question: What do SLO100, 5150 (block letter) and DualRec have in common??
Answer: The overall preamp circuitry design (by Mike Soldano = SLO100)...just some alterations in terms of gain stages/cascading here and there....don´t forget the Recto poweramp design....
Strip them all of their poweramp stage and back down to their bare simple preamp and the blueprints are not that different from each other.

YMMV.....

That's excellent SC thanks for that info.  Ok well my undertsanding of it was an MP1 was supposed to kinda be a hot rodded JCM in a box so you confirm this.

I read somewhere the SLO100 and 5150 where kinda copies of one another.  Can't remember which one copied which.  Peavey copied SLO I think.

I think my plan in future is to get another mp1 and mod it to Mod 4, if there isn't going to be much difference in what I have now 3TM and MP1+MDRTNOISEMOD then I wont bother.

This is all cool info thanks.

Hey RG, apart from the tones, the MP1 solved all the boost problems and got rid of wall warts and pedals.  So I was using my 72 Marshall 50, great amp but needs a power soak so you can be in the same room (my record with this amp BTW is you can here it (clearly) 13 kms away). So no master vol, no channel switching... So out comes this MP1 gadget, patch 01 sounds better than my Marshall and I can have 128 of them at any master vol I want  :whoohoo!: . And that's just one angle to it (as you know, you have one). Also, as MJMP said the early Marshalls were 50/50 preamp and poweramp distortion, MP1 had it all done within itself so you could use nice clean transparent power amps (even SS ie B200s), this is also largely when guitar stereo happened (and I'll never go back). Then came MP2, even better sound IMO and lots of really good features (long before anyone else developed/incorporated them). If I could buy a brand new MP2 tomorrow I would, there is nothing else available that (for me) comes even close, which is why I bought a couple of spares...  I like Marshalls, but my tone is ADA, and I've developed "my tone", I'm quite happy with that and am not interested in cloning other stuff, but that's me... I tried my 72 Marshall a little while ago (it basically sits in the corner), I gave it some new tubes (some SPAX7s that I had spare), it didn't even come close to sounding as good as the MP2 (not to malign it, it was my main amp for many many years).

I think those glammers (  :lol: ) used the older plexi and JMP amps more.Most of them were modified by guys like Jose,Friedman and Langner to get that high gain sound.Also they used the TS-9 a lot to boost it.

If you want to hear the difference listen to White Lion's album "Pride" and compare it with their next album "Big Game". Here you can hear the difference between a Marshall and a MP-1.

Ok so here is a thought then, (excludes me this question as I am impartial)

Why MJMP and Richard does a man with a love for the real thing (Marshall) like or use an ADA preamp? 

You are not allowed to say, because you can play it quietly.  I'm asking this to see if you guys answer in a specific way known only to me  :thumb-up:


Yeah MJMP I suppose the MP1 was not around for most of those bands to make their 1st and 2nd albums, may be even there 3rd so 1959 or JCM800 boosted would have been the weapon on choice.

Question: when people say "Hot Rodded JCM" are they referring to some internal built in boost to drive the amp into more distortion?  Or do they mean "boosted externally by a pedal".  I assume it's the first.

If so, what was the difference between having an external unit and having a JCM800 modified?

Hey RG, why, cause you can play it quietly in your bedroom (just taking the piss LoL), I always played mine as loud as I needed (and probably a bit more  >:D ). If you ignore all the advantages of MP1/2 compared to Marshalls of the time (and particularly my 72 50w) (eg 128 presets, master vol, chorus, stereo, midi control etc), the tone of my original MP1 and now MP2 are soo much better than my Marshall (not that it's crap BTW, just no where near as good (to my ears)). Now that's the only Marshall I still have, I did have a Marshall artist 100w keyboard variant along the way to be one side of the Rockman X100, so I was just using it as a poweramp (much like MJMP does with some of his Marshalls).

I like Marshall amps, and a few others.  I don't consider the MP1/2 "not" the real thing. They are now (well mostly MP2 these days) my sound (with my patches guitars amps speakers etc (fingers  >:D )). I've been developing "my" sound over many years with what I have at hand (and how I play)). The Marshall ("come and hear the real thing come and see"/Russel Morris) was a central part of this for many years (and no regrets, it's a great amp).  MP1/2 are on a different planet IMO (and "what advantages"/Chrissy Amphlet, Divynals, never much - happening in my life..)). Actually I was a bit shocked when I plugged in the Marshall after all these years (with new SPAX7 input tubes) how big the difference to MP1/2 was/is.

I spose I used to be a Marshall guy, now I'm very firmly and ADA guy (that's come from a Marshall background).  But I never got into the later Marshalls (why?, I had MP1/2) so I don't know much about them.

Well yes,my heads are just too loud to rehearse and too much switching around to get  clean tones etc...
That's why I use ADA's but if I'm honest the heads sound better.(about 10%  ;D )
So I sacriface a bit of sound for the ease of racks.

For me vintage stuff just sounds better.

EDITS: added a lot more to this original post and a question to MJMP!


well there we have it.  And that is what I was trying to get, what you two guys really believe.  MJMP firmly believes heads are better, 10% he will part with for practicality side but ultimately amps are 10% better sounding for him.

Richard is the ADA king!  He is 100% that ADA Preamps (MP2) is best sounding.

But I guess you both are ADA through and through really, how can MJMP be the ADA whizz that he is eh :thumb-up:

To be honest I was expecting both you guys to say something similar to what MJMP said.

Me, I don't give a f*ck.  None of it makes any difference to me, for the simple fact that, I find gear I like, I work with it, I make my own sound, and then I go from there.  I burn a candle of support only after this point (the point were I fall in love with something).

I must admit though, you guys both came from running Marshall amps, that is what you were brought up on so I can see why this favour for them still remains.  And I guess I wasn't, so I don't have that connection hence not having the loyalty.  In saying that, my first loud amp was Hybrid AVT150 combo.

I guess since I love MP1s, I've made them my tool of choice and now I've the loyalty thing to them, I'll run with them now until....well who knows.  At least them and the Peavey Rockmasters which I also love.  I love both, having those voicing's, both are different.  So I know MP1 is Marshall esque and I guess Peavey is Peavey lol.

Thanks for answering guys.

MJMP, tell me your story about getting MP1's, what was it like for you and the attraction, what where you using before and when did you go, "hey these things aint bad I'm gonna start using them also"?

and

how good do you think the MP1's are, like say you were telling me about them for the first time or recommending to a customer?

adjusted the trim pot.

OD1 still lights up quite a bit at a 7.5 setting.  Even if I turn the trim pot all the way down it's kinda similar.  Rather than have it all the way down I turned up a tiny bit.

Also do the tubes now they are getting morem voltage, glow brighter?  They look really bright now :)
Title: Re: MP1 - MDRT Upgrade + plus big noise Mod
Post by: MarshallJMP on April 25, 2016, 05:34:05 AM
Well my OD1 lights up from time to time,so no worries,you won't blow up anything.Else if it bothers you you can always lower OD1, 7.5 is quite high.

Yep they glow brighter because the filament voltage has gone up from 8.5V to about 13V

So my amp history (skipping the early years).Started out with boss pedals into a JCM800 2*12 combo 50W.Then i got my first 100W JMP head with the same boss pedals.Then boss pedals replaced by the boss ME-5.Replace the ME-5 with a MP-1 (with a boss GE-7 in front of it) and a ART multiverb alpha + an art X11 midi controller going into the front of the marshall head.This was my first rack setup.I needed a stereo sound so in came the second head and cab.Used this for many years and then changed to the MP-2 and a lexicon MPX-1 with the roland FC-200 midi controller.Then the depot came online and I went back to the MP-1 with the 3TM in.The lexicon was replaced by the TC G-force and the FC-200 was replaced by the ADA MXC pedal pack i bought new for 100 euro.And from there on my rack exploded from a 4U to a 18U which I still have now.Also went from 2 cabs to 4 cabs.

So what I use now

*Amps 2 100W marshall heads modified one input to go straight to the power amp section.One is a 66 plexi and one is 72 metal face.

*Cabs 4 4x12 marshall cabs,an old late 60's cab with greenbacks 25W,an early 80's JCM800 cab with 12G65's,a JCM900 with 12GT75 and a vintage cab with V30's in it.

*Rack gear;
Furmann PL8 + series II
Korg DTR-2
Decimator Pro G rack
Dunlop DCR2-SR rack wah
Rocktron patch mate
ADA MP-2
ADA MP-1
TC electronic G-Force

Hey RG, So the clip leds light at a certain voltage (IIRC it's in the manual where they kick in).  There is still some headroom after they light (before you get distortion you "don't" want). If they flash a bit, that should be ok (actually indicates optimum signal), you don't want them to come on solid and stay there... Are you running anything in front of MP1 ? as that can/may increase your gain.

More volts to the heaters = brighter (makes sense) and hotter BYW  >:D

@ MJMP

so you have all that stuff, and you take it every gig?  And you play in a covers band?  Holy shit man, that's insane.  I mean no disrespect by the way  :thumb-up:  I just think that sounds like a lot.  Cover bands over hear don't usually have that much shit for just one guy.

Now forgive me for making assumptions, but I assume you play similar size venues to what I do, so how the hell do you get all that stuff onstage? One Guitarist or two?

Oh and I've seen big name touring bands play with less than you, you are an absolute maniac lol

And surely you go not get to crank all that fire power?  I have never in 10 years of playing live been allowed to turn my amps up anywhere near full blast.  And I'm sure your marshall are way louder than any amps I have ever owned.

And another thing......you have a roadie?  Do you pay him?  Jesus if only I had a roadie!!  perhaps I should quit touring and stop playing my own music and I can get a roadie as well.

I am sooooo jeaous  :dunno:

Are you perhaps some famous guy and are not telling us who you are really?  How can one humble ADA wizard/studio hand/repair shop guy come to have such a big rig?

Ok Ok I'm done with that now.


Did you say at one point you had just an MP2 rig?  What do you think about it?


Ok back to MDRT+NOISE MOD business!

The OD trim pot even at zero, striking a power chord on lower strings makes the light come on.  I thought that was too much but then if you guys say it's ok sure I'll leave it where it is.  I'm not worried I'm just saying it comes on a lot more than it used too.

@Richard, not I did not have anything in front of the mp1 when I was testing it.  Actually when I stuck an OD in front for a boost it lit less, I DROP THE OD1 level though to bout 4-5 when I use a boost.

So more voltage, more glow!!  Ok I like this, I want more glowing tubes in my preamps.  I don't my 3tm glows as much?

We always carried a lot of stuff around,lot's of marshall stacks and big drum kits.You will be amazed if you put a lot of gear on stage how many people just come to see you because of the gear on stage.It's a real attraction on it's own. :metal:

I set my stuff pretty loud on stage,our drummer likes that,he wants to HEAR us out of the amps.

No i don't pay him,he's a friend and he just likes to do this.

Why so big,mmm well in 80's when you went to see all those metal bands,there were walls of marshalls and I think it went into my mind thinking one day i will also have this!!!  :lol:
And this is half i own,got a lot more gear then this.It's just the result of years of collecting.I have a list somewhere if you want it.

Yep i had a MP-2 rig but i never got satisfied with it.I always liked the MP-1 better for distortion but i loved the MP-2 cleans,so now i have the best of both worlds.

3TM maybe will glow a bit less because the voltage will drop a bit but i don't think you will see it.

Ok Ok, so I too look at all those bands and think what you think, but reality and practicality said "No will never have this or be able to take this to gigs".

Whilst this is fun and something I enjoy as a fan of big bands I personally just want people to come for our music and our performance (how boring a, I???  :lol:).  And as I am learning most of those amps on stage where props.  Aren't people talking about fake marshalls cabs on here on another thread?  Hahaha that's so crazy  :lol:  I know priest had two full cabs each guitarist and the rest where fake, so you're just like Judas Priest MJMP  :whoohoo!:

You have double the speakers I have, and despite this I can only take half mine to gigs.  I'd love to have a free roadie!!!

Generally how gigs in Ireland and UK is, someone brings cabs, and everyone uses them for the gig.  Then someone else brings the drum kit.  That's how it is.  Sometimes we have to bring all the stuff, but in sayin that I only ever take two 2x12" cabs.  If other guitarists have also cabs I can use then I'll try plugging them all on depending on what load they create.

But anyways, it's kinda unheard off for anyone to take that amount of gear anymore but this might just be where I play I dunno.  Are things like this in Belgium or is it just yourself?  We played with a Belgian band in Holland last year and these guys where doing the same as us, showing up and using gear that was supplied for them, but using their own amps, same as me.  Generally what will be provided will be two 4x12"s, one for each guitarist.  I always use both since I play in stereo so one each side of the stage.

You know if I had the capability to take as much as you (which sure would be fun :))and people to help, I would still be at the mercy of the sound man who is in control and if he tells you you cannot go any louder then you have to do what he says or else risk shit sound and feedback hell!

If I was like playing really big places I could see the need I guess for all those speakers, but even at that, you are mic'd up anyways and it doesn't matter as it's the PA you are relying on and the sound man and the monitors.

MJMP living out the dream with two marshall stacks!! :thumb-up:

Curious now as to what other guys on here play with or what the setup is like in their countries?  Lots of gear or just essentials for a backline?

Hey RG, I've used a variety of live setups over the years, mostly whatever I could afford.  These days, for a small gig I take one slant split stack (wired stereo), 8 RU rack, 2 RU rack (TS100), lead bag, 2 guitars.  For a larger (medium room) I take the 2 slant split stacks instead. I've toyed with the idea of using all 3 split stacks and using the middle on for the Marshall, maybe one day, I don't gig much these days.

Allot of the bigger touring bands seem to use 2 quad boxes per guitar (side by side) and a head(s) with a rack for FX.

I was the same Richard, what eer I could afford, started with Marshall AVT150 combo and extension cab, then moved onto a 120 watt randall RX120 head and 4x12" and used both.  Then I ditched them both for Crate Power Blocks.

Now I've the Harley Benton.  Really love this Amp, bags of power, and sounds great.  Really useful Resonance and Presence controls.  Anyways now I have been able to afford better gear but I just can't cart it everywhere, only gigs I do in Ireland and the UK.  Flying over with all the shit I would like to add to my rig will be a nightmare.  Already got our manager looking into weight restrictions for stuff on flights.  Heard a band recently from England couldn't get their ENGL Fireball over in a plane to Ireland!  And that's not very far to travel at all.

Hey RG, flying gear around without a big budget is a major pain.  Bit different if you can throw it in the truck and drive it there. And tube amps and cab (as we all know are not lite).

Post by: MarshallJMP on April 27, 2016, 02:58:55 PM
Well i'm with Richard,i think a truck or something like a Ford transit would be a much better solution.This way you don't have all these restrictions and you can take on the road what you want.

Ahhhh....but that is the beauty of the Split-Stack cabs. You can put a full stack in a smaller car and take it to a gig with your guitar(s), and have the whole thing set up by yourself like I was doing.
I used to have the 4x12 cabs, and at one time even had a Marshall 8x10 cab, but they are so bulky to transport and set up on a stage. I have no regrets about the ADA gear at all.

Just my two cents,

I do like that about my split stacks, they are much more car friendly, And I can get all my guitar gear in the back of the car. I can get 2 split stacks in, but I wouldn't be able to fit a quad box.
But if you can have a van or small truck it does make the whole thing easier and also lets you use quad boxes if you want.  Then it's a long drive from Ireland to Europe, if you have to fly due to time constraints (or distance) like all the bands who come to Australia bringing cabs is very cost prohibitive.  I think most of them just bring their heads and racks, otherwise they hire gear here.  Also driving between most Australian capital cities (for tomorrow nights gig) is probably similar in distance (if not more) than Ireland to Europe (bit less stuff/towns on the way though).

I worked on the Dire Straits Canberra gig of their farewell/thank you tour.  They even flew in their lighting truss, they hired front house cabs and amps locally.  They had each scaffold stage (all outdoor gigs) built the same so all the cables were (just) the rite length etc. Interesting show, it rained, we all got soaked, we loaded 17 semitrailers in 2 hours in the wet.  Perth took 2 hours and it was dry for them (bragging rights  :thumb-up: ). Apart from pack and load I got assigned to the foldback engineer so was lots of fun (apart from getting totally soaked)

Very true Richard,

  I put my two bottom cabs in the back seat of my Dodge Stratus, with the rack head, and my guitars, then put the two top cabs in the trunk with the foot controller, guitar stands, and mic stands. It all fits very nicely.
 
   Perth! I have some very fond memories of that city! I visited there in 1980. It wasn't a gig, I was still in the US Navy at that time, but I would love to play a show there! Just saying...

I've only got to Perth a couple of times for work and not for long but nice city. They still have a lively music scene partly because they don't allow poker machines in pubs (like the rest of the country).  I agree, it'd be nice to play a show or 2 there  :whoohoo!: .

With a midi EQ ad output you can get more diversity .
I put an Jeff loomis od sig. od and  before that the new Gary holt boosrth  both by ProTonePedals. (handbuild by Dennis Molan)
Then you can. get  nice too very good sounding high gain etc.
