Poly 800

“Korg Vintage Synth – Poly 800 with MOD

Reluctant sale, downsizing studio. Bargain

At a time when Roland was doing well with their Juno-series, KORG countered with a poly-synth of their own in 1983 with the Poly-800. The Poly-800 was comparable to the Juno-106.

Classic 80’s vintage synth from smoke free dry studio.

Modded with cut off filter. ” Click here to visit listing on eBay

“The top of the modulation stick is missing but still functions perfectly. I have a power supply but its fairly temperamental.

Selling because I’m moving away for studies.

Please check my other listings, some great bits available for below market price.”

“Korg Poly-800 Vintage Polyphonic Synthesizer, rare reverse keys model. This synth powers up but does not make much noise. The internal battery compartment/lid is missing as the batteries leaked and destroyed them. It is supplied in a home made flight case which needs some TLC, the foam smells like it’s breaking down and needs replacing. Definitely a project for someone who knows how to repair old kit. Also I believe it’s the model without a PCB mounted memory battery so will need modding. Please note this is not a usable synth as it is!” Click here to visit listing on eBay

“Was gifted this from my Grandparents as it had been sitting in their loft for 20 odd years, condition is faulty, some patches work but some do seem to have an issue, not sure if it’s the LFO or if it just needs the patches reloaded tbh, but either way it’s something I just haven’t used enough! ” Click here to visit listing on eBay

“You are bidding on a Korg Poly-800. This is a classic analog synth from the 80’s. I am the original owner. I bought it brand new back in 1985, and it has always been kept in a dry, smoke-free environment. All the keys still have their original spring action and work perfectly. The joystick and all the buttons work perfectly as well, and the display is nice and bright with no faulty segments.

Cosmetically, the synth is in great shape for its age. There are some minor scuffs and scrapes, the worst of them being along the rear of the unit. The only other cosmetic blemish of note would be the bezel surrounding the joystick. At one point, the adhesive lifted and the bezel got snagged causing it to crack (see photos). I have taped it back down with some double sided tape, but it is starting to lift back up. It should probably be glued down, but I’ll leave that to the new owner.

I am including the original Korg power adapter, the original cassette tape with all the default sound files, and the original instruction manual.” Click here to visit listing on eBay

“Up for sale is a Korg Poly 800 with full Atomahawk upgrade in great condition technically and cosmetically.

The upgrade gives 84 additional parameters which transform this already beautiful synth into a wild sound design machine while still providing you with the original parameters.

Additional parameters include frequency modulation, super lfo, aggressive resonance settings and lots of really interesting additional waveforms and modulation routing options.

Also there is no need to replace the battery for patch storage as the upgrade takes care of all of that.

One minor issue is that the dco mod stick can stick periodically. I never use this so has never been a problem.

Comes with power supply.

This is overall a really good example of a poly 800.” Click here to visit listing on eBay
