“USED Vintage Korg Polysix Synthesizer. Selling as is for PARTS / REPAIR due to age, cosmetic condition and the issues I know of.
I purchased this synth in the shape its in now, about 12 years ago. I had hoped to eventually have it refurbished but ultimately just used it occasionally, as is.
Synth powers up and is playable ( and sounds great – in my opinion! )
Keys and mod wheels work.
All knobs and switches in the “playable section” work well. (OUTPUT, TUNE, BEND, VCO, VCF, VCA, ARPEGGIATOR, MG, EG, EFFECTS & KEY ASSIGN MODE)
Known issues:
Volume knob is scratchy when adjusting – totally fine while set.
The program number 4 button stays lit and doesn’t switch when pressed. You can still switch to the other programs.
I never messed with the tape functions so I cant speak to how well they work. However, the buttons do light.
The face of the synth has some marks, scratches and scuffs. The wood paneling has some scuffs, marks, scratches and chips. The area under the mod wheel has some wear marks.” Click here to search for synths on eBay
” Very good condition- inside and out as you can see by the photos. I have been repairing consumer and pro gear since 1979 and all my gear has been well cared for and maintained to a Tee. All controls, switches and input/output jacks have been thoroughly cleaned and deoxidized. All tact switches work as if new. The electrolytic capacitors have all been checked for excessive ESR and the voltage regulators scoped for excess ripple and proper output. I have also replaced the soldered-in memory backup battery with a battery holder so the backup battery can be easily changed in the future. I have owned this little beauty for about 20 years and it has seen very seldom use. I’m going through all of my gear, refurbing it all and reluctantly letting it go. It comes with the power supply, both the Owner’s manual and Service manual in digital form (PDF) and the factory sysex downloaded directly from Korg’s website. There are several sites that you can get free patches from which can be downloaded and imported via midi or the tape input. The power supply is included but is not original. Hoping it goes to a good home that will appreciate it for what a gem it is!”

“This is a vintage Korg Poly-61 synthesizer. The Korg Poly-61 exhibits pinholes on a handful of the lower octave keys made by the previous owner. Not sure the intention or purpose of these holes but nonetheless, it is not affecting the playability or overall integrity of the keyboard. Also, each of the corners shows wear that is normal for a keyboard of this age. Overall, the Korg Poly-61 is in very good condition. The Korg Poly-61 is fully functional and operates as intended.”

“Korg Poly-800 Vintage Synthesizer Keyboard
” Selling my custom Korg poly-61 in great shape. Manual controls of cutoff, resonance, attack, decay and sustain have been added so you don’t have to menu dive for those common elements. I wired it so each potentiometer has a corresponding on\off switch for turning each parameter on or off. Midi in and thru have been added on channel 6. I proactively changed the battery to ensure there wouldn’t be any leakage or damage to the board. This year I cleaned and rebuilt the key bed. All knobs, buttons and functions work as they should. The synth sounds fantastic! The factory bank has been loaded in preparation for this sale.
“Up for grabs is my vintage Korg 700 Mini-Korg, Korg’s first synthesizer. I picked this up earlier this year at a local auction, but haven’t used it as much as I thought I would so am listing. It’s in decent condition for the age. Cosmetically, it has some scratches and looks like someone dropped their cigarette on the keys at some point in it’s life but that has no impact on performance.
“This unit has been in my smoke free studio for the past 7 years. It’s fully functional, and everything works as it should.
” Very rare and in excellent shape and was studio kept. Original power cord. Unit is in perfect working order. Some light surface scratches from wear and tear. ” 
“Works Great, Just like the Day I Bought it! Only thing is when uploading a Patch you might have lightly tap the Tape Enable switch once to see the display LEDs Flickering showing when it “Hears” the DATA, hard to explain but the Flickering LEDs is by design, but once you start loading the other 11 new patches, hearing the new synth sounds, you will understand what I am saying 100%, This is not a issue, Comes with Power Supply, Manual, Original Box, Two Midi cables, Two 6.3mm (or 1/4″ as it’s commonly referred to) mono connector Phono Cables, One Mini PC to Keyboard Mini Phono Data Cable, One Headphone Stereo mini Phono to 1/4 Phono Adapter and (See Pictures) One Factory POLY-800 Patch and ELEVEN MORE POLY-800 Patches !!!!!!!!!”

“Description- Vintage Korg Trident synthesizer all original in good cosmetic condition with a few minor scrapes and chips on wood. I had it checked it out by a professional they stated as follows: String Bank is a bit quieter than the brass and synth banks, programmer write button will not light up, brass volume pot scratchy, synth volume pot scratchy, headphone volume pot scratchy, everything works as it should will need minimal pot cleaning and lubrication to be perfect working order. Sold as is as described if something goes out on it a week or a month from now I am sorry but it is old electronics and will be new owners responsibility. I only guarantee it to arrive as described. ”
