Fell in love with the MP-1 again

[El Chiguete]

The settings I used in the beginning are TOTALLY different than what I use now! Of course everyones different rig changes the tone but I think the real thing to get used to the MP-1 is that the eq is active and does not interact with each other like the eq on a normal amp. For me one day I said  f*ck it and started trying crazy settings and guess what, they worked for me! :)

what do you mean the eq is active?  Do explain?  Perhaps with what you're about to tell me in mind might help me when programmin :)

For my live rig I have been using some unusual settings.  Like really having to drop a lot of bass for example.

By this I meen that (and I want the forum gurus to clarify) a normal eq section on an amp only cuts (basicly you have the base signal with the knobs at 10 and then you cut  B/M/T/P as you roll down the knobs but the eq of the MP-1 adds and cuts in the freqs that its eq section is made (so it works like an eq pedal/unit). This also meens that on a normal eq of an amp the center freq points actually shift around deppending where the other knobs are at and on the MP-1 as other eq pedal or units those points are fixed.

So can the gurus chime on this?

Ahhh I see.  I had no idea.  Ignorance is bliss!!  That's interesting, forgive me guru god on here I didn't know that about amps either.

Yes most tube heads  have a passive tone section,passive means it can only cut.Very simple design with a few caps,a resistor and 3 pots.Now the presence is different and  is actually sort of active since it works in the feedback circuit of the amp.Same goes for the resonance knobs on the more modern amps,but these can also be installed on older amps.
Now some tube amps did have an active EQ section,what comes to mind is the marshall major 200W also called the pig which had only 3 controls,vol,bass and treble which were active.Another example is the JCM800 bass head which also had an active bass and treble EQ.
Now the passive eq even if everything is on 10 isn't actually flat,there will be some eq'ing going on due to the design.

Here is a nice site with some more info,there's even a emulator so you can "see" how it works in the freq domain.

So EL i hope this answers your question?

Well I actually didnt made a question just wanted you to come up and say if what I said was correct or not jeje.

And yeha, by flat I ment "flat" to the design... This is also why I use those crazy settings because using a normal amp setting on a MP-1 I don't think works good because the actual design I believe is not ment to be based on any other reference amp (like when you get amps from the same brand sometimes they tend to have that Brands tone... most every Marshall after the Plexi carries that base tone but maybe shifts it a little bit to a particular sound but a Marshall sound "should" at least be a Marshall......... also with any other amp that is a clone or based from an original amp design should use similar eq settings to get a similar tone) BUT the MP-1 base tone isnt cloning anything so maybe for me when I put the Mid at -8 it gets in the ball park of a tone that on another amp is 6!

Who knows, I just say dont be afraid to play around with those settings to get a tone that you wouldnt expect unless you tried it! :)

Hey but good answer MJMP  :thumb-up: In some ways the ADA preamps were the first profiler/cloners but using the same analogue/tube circuity. You can pull up the sound of pretty much any tube amp of the time and then some ( >:D they do have their own sound though  :whoohoo!: ). They were also fore front into rack set ups (we all know/own/love). Yes you can emulate many different sounds with ADA preamps, you can also create your own sound (so totally agree EL, don't be afraid to play around, experiment, take it to the limit... and share it here LoL)
