“Up for sale is a Korg Poly-800 MkII in good, working condition. It comes with the original power adapter, user manual, and preload data tape”
“I am selling the synth as is. All keys work, it sounds great. But am unsure if it is able to save patches. Also only the Right output on the back works the L/Mono and headphone jack doesnt work so well. And the holders for using it as a keytar are sawed off. It is also missing some screws. Other than that it works and sounds great. Does not come with a power adapter but it can be run on batteries.” Link

“KORG POLY 800
i did buy it like this
all mods do sothing extra, but i cannot name what exactly.
probably, knobs are filter/resonance/FM/ external input,
switch changes waveform and noise/ext in.. but, i can’t say for sure.” Link
“Works great, no issues with it. Motivated seller. Cheaper than any other on here. No reasonable offers refused.” Link
” Up for sale is a (1) vintage Korg Poly 800 mk1 synthesizer, the version with reversed keys. It powers up, but there are a few functions not working. That’s why we sell it as-is, for spares or parts only. Almost all the presets are gone and the write-functions doesn’t work. The volume-knob and faders for the sequencer are very scratchy and the chord memory is not working.
It has some mods installed: at the left side you see two filter knobs (cutoff and resonance) with a switch. The switch and cutoff are working fine. The resonance knob isn’t working. On the back panel there’s a knob with switch and jack output. They don’t have a function as far as we can see. At the right side of the keyboard you see two knobs. One is a 5-stage switching knob with different functions. Only noise and distortion seems to work fine.
So, it’s a project or you can use it for parts. All the voices are alive. Editting is also possible.
Cosmetically it’s in bad condition with a lot of scratches on the case and keys, wear and tear, discoloring of the panel and there are some small dents. There’s no serial number on it anymore. We didn’t test it with batteries. A 9V psu adaptor with European plug is included in the sale. ” Link
“Working order. Needs one note it’s the third F that needs looking at in the curcuit. Besides that still works fine. Needs a few screws and a power adapter. I was using batteries” Link
“Don’t know much about this keyboard exvept that I have the original Korg adapter with it and it powers up. It has a broken key (that apparently can be easily ordered and replaced). Other than that, all looks great! So, I decided to give it a chance. Its gonna cost a bit to ship because of the size and weight of it (that, I have no control over) so, the shipping will be the biggest issue. Im starting the auction very cheap and not looking to get rich off of this, just give somebody a chance a obtaining a vintage keyboard synthesizer that was once very highly sought.
Be mindful that shipping depends on location. I’m shipping from the DC line and this item is sold as is.” Link
“Excellent working condition with no issues. There is very light cosmetic wear, some light dings and scratches but nothing substantial. Power cord is not included but they do also run on batteries, so the cord is not needed. ” Link
“Up for sale is a Korg Poly 800 II in excellent/Near Mint condition. Comes with original power supply (not pictured) and Original Case.” Link
“Up for sale is a used vintage Korg Poly-800 Synthesizer. There is a slight mark/scratch on a some of the white keys (as pictured) but overall it is in fantastic working condition. The modulation wheel is missing the handle cap but functions fine without it. All keys and buttons also are in great condition and work like magic! Unfortunately, this does not come with the original 9volt adapter but is compatible with other adapters. I will also send the patch list I scavenged along with the keyboard (over 200 different patches). Does not come with a gig bag but will be packaged well. ” Link
Has some velcro and tape residue, mostly on the back. I uploaded the original factory presets. All keys and functions work great. Adaptor is not original, but it works great. Volume knob is a bit scratchy when adjusting, some contact cleaner should do the trick. Fully programmable.” Link
“In Excellent working order – Includes original manual (manual has some writing in it and discoloration) and original power supply in great shape. Comes with “hybrid” case. Has some scuffs on the back and here and there, a little wear around on knob – see pictures but really excellent and tested.
A VINTAGE Korg Poly 800 MKII in good working order (this is a synthesizer you need an external sound source no internal speaker, can be used with standard headphone jack to external stereo jack input). Originally released in 1985, this is the follow up to the original version that added effects and a larger sequencer. This can be strapped on your shoulder with a guitar strap, like a guitar and be played with batteries you load in the back of the unit. you can see the battery insert in the pictures as well. everything has been well taken care of and in a nonsmoking environment. Everything works it may need the lithium battery to hold your custom settings you want to save as this is vintage (not sure when last changed), these are only $4.69 on ebay right now.” Link
“The item is in good looking condition ,it starts properly and has all the programs, but some keys are not working or need a lot of pressing and the joystick with the tune fader (I think) does not functioning properly ,output to headphones is ok, and all the other buttons and features seem ok.Please feel free to ask me anything ,I think for someone who knows electronics is easy to clean the keys and fix it.(Photo is taken from internet but item looks almost same condition)” Link
Works flawlessly, except for one key in the higher register.
Had no real issues with this unit since ownership (2014-17), except for the one key mentioned above.” Link
Very good physical condition. Turns on but the sounds don’t work. I’m pretty sure the sounds just need to be reloaded via the tape in jack. Should be a great deal from someone who can easily fix this.
Sold as-is.” Link

“Synthesizer in mint condition, comes in original box. Power adaptor is not original, but a functional universal adaptor.”
“Unique synthesis method however programs don’t save. I believe a tape drive will allow it to store programs or it might just need a battery. ” Link

There is a modification that adds two knobs to the VCF, increasing the filter’s range and expressiveness, known as the Moog-Slayer filter modification; the FM-800 filter modification which adds a pseudo FM control to the filter; a modification for external audio input; and some users have added a switch to control the filter slope, adjusting it from a 4 pole (24db/oct) to a 2 pole (12db/oct).
As you may have already read, the Poly 800 is a paraphonic analogue synth (all but the DCO’s, which, if anything, ensure that the oscillators stay stable).
Without the mods the keyboard is fine, but with these additions, the instrument can attain a decent range of expression.
A great synth, with multiple applications, the Poly 800 is one of the cheaper ways to get your hands on that analogue sound. ” Link
“Synthesizer is in good condition. I ran through the various programs and played with parameter values and all buttons and functions are working properly. Synthesizer looks good overall but does show cosmetic wear from prior use. Original AC power adapter is not included but a non-OEM adapter will be included. This adapter is a little under powered (lower amperage than original) but works okay. I will also include 6 new C batteries, which you may use as an alternate power source.” Link
Habe den Synth nie so richtig verstanden und unter Kontrolle bekommen.
Er hat manchmal einen seltsamen Aftertouch auf den Tasten, wie eine Art Modulationseffekt (Habe nie gefunden, was das sein könnte), deswegen habe ich ihn bisher für fette Flächen und warme Bässe einfach per Midi angesteuert.
Original Netzteil ist dabei!” Link

The unit is in excellent condition (please see images). The box has the original polystyrene inserts.
Some of the keys on the keyboard do not sound, but I have always used it via midi where this is not an issue.
Batteries and power supply not included.
There are a couple of marks (please see images), nothing that affects use.” Link
“Beautiful condition Korg Poly 800 II. It is in excellent working shape, Has a few tiny scratches but excellent for a 35 year old synth. It comes with the original power supply, a copy of the manual and loaded with excellent patches. I’m including a gig bag as well (not pictured). ” Link

“Here’s a KORG POLY-800. This is a true Classic Vintage Polyphonic Analogue Synthesizer straight out of the 1980’s in GOOD cosmetic condition, and perfect working condition. Display is bright, and crisp. Always used and stored in a smoke-free studio environment. My father is the original owner of this synth. He’s an accomplished, successful Motown/Soul/R&B artist, and a complete gear-head. His studio is too cluttered with too much vintage gear that he’s collected throughout his 30+ years in the music business, so I finally convinced him to let some of it go. This synth is getting some much deserved attention recently after being used in the productions of Synthwave and Vaporwave artists. His loss is your gain! ” Link
