“Korg Poly 800ii, Key contacts were all cleaned, all keys are working as they should. Sliders all work- Pitch and mod work- Part of the trim ring around pitch level looks like it is missing. Has brand new power supply. Not sure how the sequencer works, was able to see it stepping thru, however I don’t know how to use it. Unit has some scuffs here and there but is good condition for its age. Tuning slider cap needs replaced but slider pot still functions fine, just a cosmetic thing, Some really cool sounds on this unit. ” Click here to search for synths on eBay

“Up for grabs is a VINTAGE Korg Poly 800ii synthesizer
“Up for auction we have a Korg Poly 800 Analog Synth. Overall this synth is fantastic condition. Its been kept in side its hard case for most of its life sans the occasional gig, practice or recording session. Well loved and care for these Korg Poly 800s are awesome! Kind of like an alternative to a Roland Juno 106. Its much smaller and has a different set of sounds.”
“KORG POLY 800 MK1 New Battery mod and the Moog Slayer/ FM Mod
“Up for bid is my 1986 Korg Poly 800 II. I acquired this Synthesizer back in August, and after some use in my collection, I’ve decided to let it go. The keyboard itself is in good condition, but you can certainly tell it was a well loved synth. There is wear on the finish of the plastic, which reveals a shiny undercoating, however this does not affect the playing quality at all (see pictures for more details). It has a set of custom patches pre programmed through midi, so if you want the stock factory patches, I can certainly do that for you if you send me a message. It does come with a custom fitted gig case, but if you don’t need/want it just let me know! All of the keys are in perfect working order, and there are no mechanical flaws whatsoever. It also comes with the original power adapter. Thanks for looking, and happy bidding!” 
“Korg Polly mk2 with Moog slayer mod. Comes fully working. Generally the condition is good but, it is old and does have signs of use. There is also a faint postcode that has been written with what looks like a security marker pen, but is hardly noticeable.
“This is a used item. Not sure if it works or not” 
“This item is for parts! No returns!
“Spectacularly preserved Korg Poly 800 analog synth with hard case, original manual, original factory preset cassette tape and original power source. We recently purchased it from Switched-On in Austin TX and it has been fully serviced. It can be battery operated and has pegs so that it can be strapped on and played as a keytar (awesome). ” 
“Battery compartment door is missing. It powers up intermittently and display shows “Load” when it powers up.
“Does not power on. Body was opened to look inside. Maybe you can fix it? I don’t know how.”
