Korg Poly 800

“Here’s a 1980s Korg Poly-800 polyphonic synthesizer in good playing condition. This machine is a little funky to program but once you get the hang of it you’ll find that it’s loaded with a wide variety of lush and dynamic tones, and the design is nice and compact and well made. Very cool! Sure to make a great addition to your studio or live setup. Some normal cosmetic signs of use throughout (see photos), but this one is in very good shape overall.” Click here to visit listing on eBay

Korg Poly 800 Project Machine

“Up for sale is a Korg Poly 800 from the early 80s. It works but has a few issues, at some point, someone removed the write “program enable/disable” switch from the rear of the unit

and moved it to the top of the unit in the form of a mini toggle. It still works to save patches, but has to be massaged just right. All the original patches have been wiped clean, so every available patch (save a few that I’ve programmed) will need to be created to your liking and saved. There is also an added RCA plug and knob control (don’t seem to affect anything). All the keys, modulation stick (awesome) and editing functions, adjustment controls seem to work fine. I have not tried any sequencing or MIDI. Basically, this synth works but is not quite in fully working factory condition. It may need repair to fully perform as intended and is being sold as-is as a project, or for parts. There are fresh batteries installed so all patches created have the ability to be saved. Thanks for looking!” Click here to visit listing on eBay

Korg Poly-800 with Mod

“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

Korg Poly-800 with Reversed Keys Project Machine

“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
