“Vintage Korg Poly 800 Polyphonic Analog Synthesizer in VERY GOOD WORKING COND!. I purchased this unit back in 1982 and has worked great since. It is missing the battery cover on that back and thE power supply is not original. I had an extra sega genesis power supply and it powered right up. This is a really nice keyboard. Has some cosmetic imperfections but overall very good condition, considering its age. ” Click here to visit listing on eBay

“This synth has been tested and sounds great!

It has been fitted with the Moog slayer mods for control of cutoff and resonance via the knobs on the side. There is also a third knob for FM. The order of these from left to right goes; cutoff, resonance, fm.

The only issues are that the battery cover is missing and the cap for the tune slide pot is missing.

Please see pics for further detail

Also be aware 9v power supply is NOT included in the sale” Click here to visit listing on eBay

” This is a vintage analog Korg Synth from the early to mid 80s. I bought it used in the early 90s. Works great and is loaded with the original factory patches. I recently spent about 10 hours of time with this unit transfering old song parts to the computer, consequently I know it’s working just fine. The original AC adapter stopped working and has been replaced with an Archer AC Adapter with the proper voltage and miliiamps. There is a security plate attached to the bottom of the unit that I used to secure the keyboard at a live gig. I’ve also etched out (removed) my name and ID number that I engraved on the bottom of the unit. Happy bidding.” Click here to visit listing on eBay

“Up for sale is my Korg Poly 800 synthesizer with “Moogslayer and FM800″ Mods. I have had it for several years and don’t use it so much to shake the walls anymore so hoping it will find a home that it will get some use in. It works and sounds fine with all keys and MIDI functioning great and the memory battery was replaced and moved from the motherboard a couple of years ago for a longer, leak-free life. I am selling it AS IS WITH NO RETURNS since it is modified and has a couple of issues addressed below.” Click here to visit listing on eBay
