Korg Poly 800

“The unit has been thoroughly tested and is in excellent pre-owned condition as photographed. This is an earlier version and is ready to be played or modified/upgraded. No condition issues to note, this is a pristine example of this vintage synth in it’s original tour hard case which is also flawless. Made in Japan.” Click here to visit listing on eBay

Korg Poly-800

” Very good condition for its age, everything works, all keys are in good working order, all connections on the back are perfect working condition. The numeric buttons do double click sometimes but its not too bad if you use a light touch, perhaps would benefit from being cleaned somehow.

One small pin hole on the top left corner of the synth; which fortunately is where most people put the filter cut-off knob for the slayer mod.

This synth is un-modded, and includes 6 batteries which are essential to keep the patches loaded. Ideally somebody should add the battery mod and Moog Slayer mod for filter cut-off.” Click here to visit listing on eBay

Cosmetically the unit is in great condition for its age.” Click here to visit listing on eBay

“Up for sale is my Korg Poly 800. I believe this to be a very early production model because when I installed the internal CR2032 bettery, there wasnt even a symbol on the circuit board designating where its supposed to go. Other early models had the schematic symbol for the barrery, but no battery. Then later, they came with a battery.

Anyway when I got this it barely made any sound. I retrofitted a CR2032 lithium ion battery(still correct for this synth),did a factory reset and now it works great. There is a chip taken out of 1 key but it is cosmetic only. Also one of the black keys is less sensitive than the other keys but still plays just fine. Also at some point, someone stenciled the name “Johnny Hott” on the back. I found it too hilarious to dare remove it.” Click here to visit listing on eBay

Korg Poly 800 with Reversed Keys

“Works perfectly and sounds great
The number keys that are used to select the patch numbers can be a bit sensitive.
Sometimes you’ll press a key and it registers as two presses if you don’t take your finger off in time.
Maybe the keypad needs a clean. It hasn’t bothered me at all.
This is the version with the inverted keys.
No modifications, you still need the D type batteries to run the patch memory.

Cool synth, I just don’t use it very much.” Click here to visit listing on eBay

Korg Poly 800II

“You’re looking at a vintage Korg Poly 800 II keyboard. I’ve had this keyboard for a long time, I used to be a collector.

The keyboard is in good cosmetic condition, it turns on and works, you can bend pitch, tune it, lots to play with, it sounds amazing but one key does not play, it’s the 7th white from the right. I’m not sure what’s up, probably a loose wire, I thought it was worth noting. I love this thing, sad to sell it.

It is powered by a DC9v but that is not included, synth only. ” Click here to visit listing on eBay

Korg Poly 800

“Korg Poly 800 Synthesizer. Condition is “Used”. Purchased new by seller in 1980s.

NOTE: This synth has a battery that is soldiered into motherboard that is no longer charged and must be replaced for full, original functioning.
Two broken white keys have been replaced many years ago. No other problems. Synth Includes all original paperwork; the never-used reprogramming cassette tape; and Roland AC/DC 9 volt output power supply.

Great synth that was used to help me learn to play songs and many guitar solos by programming passages into the sequencer, varying playback speed, and practicing along with synth. Never used at gigs or on stage.

In the current condition, synth will produce sounds, but it needs the motherboard battery replaced to get all features working and produce proper tones. Battery compartment for the six C-type batteries used for playing without power supply contains no batteries.” Click here to visit listing on eBay

Korg Poly 800

“Unit has the regular signs of wear and tear as highlighted in the photos. The joystick’s top little nub is missing, but that doesn’t affect functionality. Guitar strap knobs will be included in packaging.

NOTE that this unit does not “remember” patch settings for longer than a few hours. I chalk this up just to its age – the battery pack in the back of the unit is supposed to power the system memory, but it doesn’t. I leave that up to someone more dedicated than me to fix. The unit is definitely a little fussy, as anything this age would be – I’ve had to open it up and blow it out several times in order to get consistent audio output. Pots are clean as a whistle, though. Sequencer is strong, MIDI functionality is great, and you can get some serious bass lines out of this instrument. I’m selling it to upgrade to other gear in my studio.” Click here to visit listing on eBay

“For sale, a vintage Korg Poly 800 that will be sold as is for parts/not working. This Poly 800 doesn’t power on and most likely needs a new internal battery. Some additional repairs may be necessary as well. The synthesizer exhibits wear such as the tune slider cap being cracked but is in otherwise, good cosmetic shape. This is one of those synths that really deserves a tech to restore it to its original glory cause the Poly 800 is awesome! A true rival to the also famous Roland 106, the Poly 800 features a stereo chorus effect, chord memory, a simple built-in sequencer, three digital envelope generators (for the oscillators, the noise generator and the filter), and a funky joystick used to adjust the pitch, modulation and the filter.” Click here to visit listing on eBay

Korg Poly 800 II

” korg poly 800 mk2 digital/analogue synthesizer. This synthesizer sounds fantastic. It has 2 DCOs and a noise generator each with their own ADSR envelope generator and most importantly it has an analogue VCF filter which makes this instrument sound great. It also has onboard digital delay, basic step sequencer and a MIDI interface so that you can sync it it sequencers, drum machines and computers with midi compatibility. Everything works on this unit except for 2nd D# key for some reason. The D# note still sounds if you play it from another controller keyboard or a sequencer or using the pitch bend but the actual key doesnt work when you press it. All other switches, sliders, knobs and keys work. It is 8note polyphonic. It comes with a real manual that you can actually read and it still has the original data tape cassette with it for factory sounds, though I have never used the tape and can’t verify if the cassette works or not. It still has the original box. I have not got a power adaptor for it but it uses the standard guitar stomp box 9V type. The original korg one broke many years ago and I just use my guitar stomp box adaptor with it now. This was the first synth I ever bought back in the 80s when I got my first job. I sampled it to death! Sorry to see it go. ” Click here to search for synths on eBay

“korg poly 800 with moog Filter Mods. Condition is “Used”. Fully working except for internal sequencer clock- sequencer works fine with an external midi clock, I haven’t investigated why this is because I always play it manually or sequence with a computer. A few cosmetic marks detailed in the photos. These weren’t made by me!!

I bought this a few years ago, installed the filter mod which works really well. It’s been great, sad to see it go but I’m moving to a smaller studio and need to move to module style synths to save space.”
