Korg Polysix

“nice synth in good shape. no manual, i have used the synth and it seems to work well. i am not 100% sure every button and light does exactly as it is supposed to, in tune etc, i mean, theres a lot of lights and buttons, it gets confusing, but i will say i believe they do. no weird noises, pots aren’t scratchy etc…see the pics, overall in good shape, the “wood” corners are a little beat but inside its clean, replaced battery and no corrosion from the old one so thats a real positive! i would recommend having it looked at for performance/safety sake but other than maybe some slight adjustments i would think this bad boy is ready to go. ” Click here to search for synths on eBay

Korg DW-8000 Project Machine

“Up for auction is a Korg DW-8000 digital wave but analog filter synthesizer. 8 voices, digital delay, scuffs and scratches, definitely not mint condition. So i have a working DW-8000 that i used to test each board in this synth and the only thing that doesnt work 100% right is the main CPU board. Some of the symptoms are not being able to edit all perameters and the arp section doesn’t seem to respond at all. The filters and oscillators are fine so is the power supply. All the keys work and in good condition.

So if you think you know whats wrong with the main cpu board then this is for you. or if you have a DW8000 and need a part other than the main board this is for you.” Click here to search for synths on eBay

Korg Trident Mk II

“Selling my 1982 Korg Trident MK2. It’s in fabulous condition considering it’s age and has just been fully serviced, tested and tuned by the synth guru that is James Walker. I also had him install the CHD Elektroservis midi kit so it’s as bang up to date as it’s possible to be.
The bodywork is a bit bruised and the underside of a couple of keys have very small chips in them, although nothing so bad that it’s offensive and definitely doesn’t affect the playability. It could easily be made to look better with a bit of French polishing TBH! If needs be I can give you a number for a guy who will build a brand new hardwood chassis for it for a decent price. ” 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

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
