Messed Up Pot Knobs

Hello, on my Microkorg's pot knobs 1 and 2, the values sometimes change on their own after adjusting. The values tend to get lower as if turning counterclockwise. Any advice on maintenance or repair of this problem?? Thanks

Ok, over 200 views but no responses. Maybe a better question would be..... Is it difficult to replace the pots?

Replacing Potentiometers on MicroKorg

Hey there,

I'm on my 2nd MicroKorg (traded the 1st one for a Snare Drum). Both of them had volume knob troubles(crackling and cutting out), and the one I have now has a problem with the 1st edit knob (the one with "cutoff" above it).

After you try Deox stuff, if you have decided to opt for surgery, just remember that you can totally fry this thing if you aren't careful. Never leave your soldering iron on the board for more than 2 seconds, and make sure you have a soldering pump and soldering braid to get the bum components out.

I've done several DIY synth projects in the last 6 months, but minutes ago I replaced my volume knob with these ones at parts is parts

So far so good!

More to your question. I'm about to try replacing the CUTOFF knob I'll post when I'm done to let you know how it went.

Wish me luck!

Edit knobs 1-5 are a different potentiometer than I thought


I guess I looked at the parts list wrong in the service manual. I ordered 2 volume pots. Some day I'll grow an attention span.

Anyways, I'll be ordering these guys(plus a few spares), again from parts is parts, since I couldn't find them elsewhere.

Still ahead of the $65 bench fee and 1/2 hour to 1 hour of labor for taking it to the shop.

Looking forward to having the old girl purring again. I toured about 180 days a year for 6 years with this little lady, so she deserves some love.

Will post when I do the deed.

Knob 1 / Cutoff knob replaced

Okay, so I switched out the 10k pot for edit knob 1 and she works like a charm.

It wasn't too bad at all.

If anyone is looking to try this same thing, I would say try removing components from an old alarm clock that you don't care about first. Make sure you can remove through hole components without tearing up the board. Then as far as soldering skills, if you can build an atari punk console, you'll be alright doing this.

Good luck

I have a similar problem - the first knob (cutoff) doesn't work.

When it's in play mode and I turn it it changes the cutoff just once (turns it down) and after that it doesn't work anymore.

In edit mode the setting on the display just blinks and doesn't change, as if I can't find the right setting.

The other knobs work fine.

Has anyone had a similar problem? Is it repairable (easily)? I hope it's not a software problem or something expensive like that...

Anyone? Without that knob I can't do anything, I can't turn the write protect off so I can't write new sounds, I can't do a factory reset...

Please help :?
