Is this the unit I shipped you?

Also did you check the bias current when you replaced those mosfet's?

Laptop RAM memory is not that hard to upgrade, I've done that to all my laptops. I guess it's quite a challenge on some older iMacs, but that's another topic....I don't use the display on my laptop at all, just the bigass TV. 

The TV was handy when my eyes were bad, now that they're fixed, it's way better.  I have tons of real estate

Yes, the current Mac Magic Mouse is sleek on top and has all the clicks and a (hidden) scroll wheel....HOWEVER, the charging cable port is on the BOTTOM of the mouse. You cannot use the mouse when charging.  That is a design flaw

As for advice on buying a Mac, I've always gotten refurbished machines that were 2 or 3 years old. Half the price, still reliable as hell and usually come with Apple care (from a reputable dealer). Sure, they may use a chip that's been improved, but I don't need the latest greatest CPU...

Hey greenmeanie, so the factory presets are stored on the EPROM and you can load them into user memory (onboard RAM chip maintained by the battery, i.e. battery goes flat, RAM dies user presets are lost).  There are 39 presets with the v1.41 EPROM (you see EPROM version when you turn it on).  If you do a load presets, it loads the 39 into the first 39 user presets IIRC and leaves the rest alone.  The 3rd from last button "compare" selects between preset and user.  If you select preset you are accessing the presets stored on the EPROM.  You can edit these but you have to save the result to a user patch.  So they are always available regardless of what you do in the user banks.  This is described pretty well in the manual.  The presets were never documented so I went through them all and documented them, took some time, I made a table in word and my daughter typed them in as I went through them.  I've posted these before but I've attached them for you.  The word doc is in patch order, the .pdf is sorted in voice order and colour coded to group each voice.

There is no reset jumper, when the battery dies (and they do eventually) you have to solder in a new one (3v lithium) or solder in a vertical battery holder with a CR2032 3v lithium button battery).  You can measure the battery with a multimeter, IIRC when it drops below 2.7v (ish) it will stop working and all in RAM will be lost.  So either save your programs (that you care about) to PC or better, write them down.

Hey Harley, if you go for a high end Macbook Pro it should do everything you want and work fine as a "DAW" and also for video.  You shouldn't need a new desk top as the latest Laptops are as good and often better.  And if you need a couple of extra monitors, as Dante says you can use the HDMI out to connect one.  I suggested the hub/dock thing as it gives you lots of additional connections to plug in a mouse, keyboard, monitors etc. (network port as well if you need it, which the Macbook Pro don't have, they use wireless).  I'm really happy with my hi end MSI laptop, I usually run it with the dock and additional monitors but can take it with me and use it stand alone.  Big upside with the Mac laptops is much better battery life between charges.  That's the one down side of my MSI, it's good for 3 to 4 hours only.  The M3 Max I suggested is 22hours, impressive.

Edit: Had a look at a friends Macbook Pro tonight, great news, the mouse has left and right click and scrolls in the middle, even better, it has no cable to connect to the Laptop, you just have to charge it up from time to time.  Even better apart from being really sleek, the top is continuous, no cracks for dust to get.  Very elegant design. I don't know how easy it is to add RAM to a Macbook, some laptops are easy and some are a pain.  Mine (MSI) allegedly is a pain so I ordered it all loaded up with 64GB so I didn't have to think about it later.

Hey Dante,

   That's a pretty good analogy comparing it to integrated stereo systems, I never thought of that, but it's pretty close.
    I usually just break down the basics of a guitar amp like a Fender Twin, or Vox AC 30, or a Marshall Bluesbreaker. All of these are the same thing: a preamp, a power amp, and speakers. You take away any one of these three things and you don't have an amp. As for effects and how they fit into this picture, I like to throw this idea into the picture: Every guitar player knows what stomp box pedals are, because we all started with them, and plugged them into the front of our amps. A lot of those effects do sound better in the front of an amp. Other effects sound much better in between the preamp and power amp.  A rack system lets you put the effects where you want them.

    Here's another question people ask about rack guitar systems: Why would you want a rack type of guitar amp?

  Let me throw out a bit of history of how rack components came into being. In the late 60s and through the 70s into the early 80s, guitar players were using pedals for effects as I mentioned earlier, but many of these things were noisy and some were kind of finicky because they were cheap circuits trying to emulate tricks done in recording studios. Remember the echoplex, or early phase shifters? These are things done with tape decks in the studios. Well, these things evolved into fancy studio processors and sounded so much better than the pedals. Well, now all the high-profile artists got the idea that they wanted to take these studio-grade effects that they used on their records on the road with them when they toured. They bought these high-end processors and had their amps modified to send out line level signals that they could put in these processors, and ran the outputs to separate amps and speakers to duplicate what they did in the studios with the same fidelity. It worked. Stomp boxes got kicked to the curb, and rack processors like Lexicon, Eventide, and a few others were hitting the road and playing arenas around the world. This went on through the early 80s to 1987. That's when Dave Tarnowski saw an opportunity to turn the amplifier industry on its ear, and brought out the MP-1. Now, you could take your preamp signal and insert these processors in between your preamp and power amp, and have all your effects that you want. Plus, he came up with the ideal of making the preamp, which is your basic tone shaper, programmable and allowing you to get any kind of amp tone you wanted from clean to gnarly distorted, and save every single different sound you wanted in a memory chip. Now, you didn't have to be like Joe Perry and take 25 amps with you to every gig. It worked. By the NAMM show of 1988, everyone was making programmable rack preamps. The history speaks for itself.

I bought a used Mp2 and did the Factory Reset but the user entered presets seem to stay? So I opened it up looked for a reset jumper didn't see any and the battery seems permanent on the board.
Is there a way to bring the user presets to what the Factory shipped it with like on the JMP1?
Also is there a list of the Factory presets? the manual didn't list them and say how many they had when new.
Thanks

@ Dante,

    I know you've been using Macs for a long time, and you swear by them. I don't know how many other members here use Macs so it's a singular point of reference, but you seem to not have issues like I've had.

    I've never used GarageBand or Logic. I've heard other people heap praise on Logic, but not too many talk about Garageband. I also remember you not having issues with viruses and other stupid things that Micro-shaft users have to watch out for.

    Anyway, as I told Richard, I'm only looking at a laptop right now to see if it's going to work out. What I'll be looking for is: how well I can navigate my way around the Mac OS, how well I can connect my audio hardware and install my software in it, and how it will handle it. I'm not really looking to use the laptop as a full blown DAW, but at the most maybe as a portable studio recording device with a smaller interface. If it holds up with what I've got now and doesn't drop its connections with the hardware or glitch the software, then I might consider upgrading to a more powerful desktop.
   If you have any suggestions or recommendations about what I should be looking for in a Mac, (like Richard has), I'm open to it. This is all uncharted territory for me.
   I should mention that when I do get the laptop, I mainly want to use it for networking and maybe shooting some video content on it. I can't do that with any of my pcs because they won't even hold together just trying to make audio recordings.

@ Richard,

  I'm not too concerned with running multiple monitors since I'm only looking at a laptop. I don't do that with them anyway.

   Since the price point is pretty close on both, and I'm just sick of win-blows, I think it's time to try something different and see how that works out.

  I know that Focusrite claims the 18i20 will work on Mac as well, but the real question is will it work the same way it's working now? I've always dealt with issues using software that needs a lot of processing power with Micro-shaft PCs, even when I built my own using the best processors, motherboards, etc., and still had these kinds of issues.

   I'm going to go with a good laptop to start with and install my interface with it and see what I get when everything is installed. Then I'll have a better idea if it's the interface or the pc. One thing I can tell you for certain, I'll never get another Dell for as long as I live. We got new computers at my job just two years ago, and they are total garbage. We are constantly calling I.T. to help resolve issues with these damned things. Yep, you guessed it, they're all Dells.

Yup - Nearest to the Front (I should have rotated this to match the PDF)
NOTE: you can see the Volume & Presence knobs at the bottom of the PDF (just noticed that)

Not really sure, compare it with the pcb. But from what I can see the jacks are in the back so I "presume" that these are at the front. So double check it when the unit is open.
