Ha, sounds like my friend/bandmate’s ms10. It could probably be fixed up, but might be expensive… then again maybe it’s as easy as just re-soldering some dry joints and spraying some contact cleaner in the knobs.
I actually kinda liked the sound of my friend’s beaten up ms10, well, until it failed completely!
I’d probably buy it, but just because failure is what I like best about analog synths, haha
