Korg MS-04 Project Machine

“A rare analog modulation pedal from Korg. Alas, I bought it to fix it, but I don’t have the time to get it going again. IT IS MISSING THE BASE. Battery-powered. Cool vintage piece. The circuitry is pretty simple, so it shouldn’t be too hard to fix. It was often paired with the Trident, I believe.” Click here to search for synths on eBay

Korg Mono/Poly

“This is my used Korg Mono/Poly synth. I’m really sad to let this go, but I just don’t have the studio space for it anymore. This was well cared for in a smoke-free environment, but it did sit in a closet for years until now and it got a little dusty. I just tested it and cleaned the surface, and all oscillators and features seem to be working, but there are a few keys that seem to need a little extra pressure to respond (all of the keys do work), but even after I played it for a few minutes the issue seemed to clear up and those keys got more responsive right away (specifically: the G2 seems to take a little extra pressure. B1,F2,G4,B4 just slightly delayed but quickly improved).. so I suspect that it could just use an internal cleaning, maybe even a blowing out would fix it up? The rest of the knobs and switches are intact and working. The volume knob was scratchy for a moment but that went away after a few rotations.
The physical appearance is fantastic. There are a few small dings on the edges, but it looks really nice. Check the photos.
If you’ve never played a Mono/Poly, this is my favorite vintage synth. The mind-bending rumbling bass and inter-planetary sounds you can make with this device make it super-fun to waste hours on tinkering! After testing it out for a few minutes I almost changed my mind about selling it!!” Click here to search for synths on eBay

Korg Poly-61M

“Serviced one month ago at the excellent keyboard repair department of Main Drag in Williamsburg, Brooklyn, this Korg Poly-61 M works perfectly, has cleaned pots and switches, and comes with all the original factory presets on board. Has a few cosmetic dings and nicks on the wooden side panels, but otherwise like new. Condition excellent / very good. RARE. This is the only one I’ve ever seen. Arpeggiator and joystick plus the chord memory feature make this a unique addition to anyone’s analog keyboard collection. Great for the ‘Stranger Things’ vibe too. Gritty 80s basses, weird squiggly strings, fun to play with the joystick to modulate the sounds.” Click here to search for synths on eBay

Korg Polysix Project Machine

“Korg Polysix Analog Synthesizer with Flight Case

Please note that the battery has leaked and refer to the photographs. Ships to the lower 48 States Only.

This Korg Polysix powers up and the keys respond but I am uncertain if it is in tune. The notes seem to go up and down the scale. I listened on headphones and also ported the audio out to a keyboard speaker. I noticed several pots were scratchy and/or intermittent so this synthesizer definitely needs servicing. I have not tested the presets as I don’t know how.

This synthesizer is not fully tested as I don’t have the experience nor the expertise. Outside of this basic test no further testing has been done so this sells as is with no guarantee and no return. Sells For Parts or Not Working. This Korg Polysix is cosmetically acceptable, please refer to the pictures. The flight case is in acceptable condition as well.” Click here to search for synths on eBay
