Yeah definitely not a feature exclusive to the MS-20, more of a character trait of analog filters. This is the first real piece of analog I've ever gotten to spend a lot of time with. You can only learn so much via the internet, ya know?

  • Remove the screws from the endcaps and pop them off.
  • Remove the three screws along the top edge of the back.
  • Flip the panel assembly forward (gently, as some of the cords are a bit taut) and unscrew the bracket that props it against the back of the case.
  • Remove the four washered screws that hold the panel cover to the main board's spacer bracket/cover. Remove all the knobs. Unscrew the nut from the headphone jack (it's the only real nut on the outer panel) and remove it and the washer behind it. Lift off the panel cover and set it aside.
  • Remove the screws holding the spacer bracket to the main board. Remove the nuts from the pots that have them (VCO1/2 waveform and octave, HPF/LPF cutoff, main volume.) Gently lift off the spacer bracket. You now have full access to all the trimmers. You can safely set the main board in place on the back of the keybed, angle it against the back of the case, and operate the synth as normal without shorting anything.
Reassembly is a simple reverse order. The only minor gotcha is that the volume knob is mounted on a separate mini-board and placed in a hole in the main board, so you'll want to make sure it's all properly aligned in its hole before replacing the nut that clamps it to the spacer bracket.

The trimmers for tuning are the ones down in the lower-left corner of the board. (To the best of my experience) the top-leftmost is the keyboard CV adjust; the one below it is VCO1's coarse tuning. The top middle trimmer is VCO2's coarse tuning; the one below it is VCO1's fine tuning, and the bottom-rightmost trimmer is VCO2's fine tuning. No, it's not a very intuitive arrangement, but whaddya gonna do.

This is quite a bit of good info, thanks! I'll be archiving it in my email account, so I'm sure it will come in handy in the future if I ever need to retune it.

Does anyone have any of the electribes? The knobs on those are all kinda wobbly, but it's never really ruined the machine. Just curious if the pots are similar to those on the Ms20 mini. I may be a little ambitious Commodorejohn, but if there is a lot of space inside, could the board essentially be moved away from the panel and custom pots/jacks be put in place?

Which Electribe? I have an EA-1 and an EMX. They're not as wobbly as the EA1, but they aren't as firm as the EMX. If you believe what you read on the internet, people act like the knobs snap off if you even look at them for too long. They're fine, trust me.

Hahah, I have an es1 which has somewhat wobbly knobs. Thanks for the input.

There's about a quarter-inch of space between the panel and the board, so that's what you'd have to work with; all the pots except the volume control are mounted to the board. The knobs on my Mini aren't especially loose; they're not firm, gotta-work-to-turn-it things, but they don't go all over the place easily. The only one I really have issues with is the VCO2 pitch knob, and I think that's as much in my fingers and the use of a small knob for two octaves' worth of tuning range as any instability in the pot itself.

Just tested one today in the shop , was really enthusiastic but was extremely disappointed... the build quality is horrible and the small keyboard is ... small. Knobs are very wobbly. I think there was also an issue with the display model as it was very very noisy and had a kind of click when pressing keys so not a good sign... I went with the Novation Bass station 2 and i feel made a good choice.

^ The noise is normal, but the click is indeed strange. Some people over at Muffs are complaining about it as well... :|

God, I love my MS-20 Mini. Sat down with it Saturday and Sunday night and just made up an entire track on the fly, and had a total blast doing it. It's a versatile piece of gear, but one that kind of suggests its own directions by its character; that, to me, is the mark of a really good synth :)

Great synth. I've had mine for a couple weeks now. If it was a person, it'd be a crusty old punk. It's not perfect by any means. Yes, it has audible noise, gate thuds, and purposely overdriven filters....but it is what it is. Get this, my minikorg also has clicks in it's VCA. I don't think anyone ever mentioned it before. The sh2 has gate noise with a closed filter. The Octave Kitten....don't even get me started. It's f**k brash, piercingly sharp, and has layers of contrast in it's dynamic range.

You're simply swimming upstream if you want mellow, floaty, jmj sounds.

I'll be posting my demo soon, which will include modulation with the Paia9700s.

^ Neither my SH2 nor my vintage MS20 have such gate clicks in the VCA, regardless of settings... Nothing like what I heard from some people's demonstrations on the mini MS20...

I tried one out in a store a few weeks back - I was listening out for the gate 'thud' that I've read so much about, but couldn't notice it. That was with headphones too.
The VCA white noise was noticeable, my 2 old ms20s don't have it but my ms10 does.

Either way I wouldn't call it a deal breaker by any stretch of the imagination.
