“This is a unique vintage Korg Maxi-Korg synthesizer. This synth is also known as the Korg 800DV. This Univox K3 was sold in the US under the name Maxi-Korg K3. The power of the Maxi-Korg lay in the way it could create and play sounds. In essence, it was two Korg 700S synths in a single box, so you could treat it as two distinct synths, creating two different sounds, and then playing them independently. Some other mid-’70s synths allowed you to play two notes, but these used the same patch parameters for both. Only the Maxi-Korg could produce two sounds that you could play as a composite, or as two independent synths. Yet this was only half the story, because the 800DV allowed you to allocate the voices in a huge variety of ways. This made it possible to program more realistic, more expressive, or more off-the-wall sounds than was possible on other monosynths. The Maxi-Korg was, and remains, one of the most impressive, flexible and articulate synths ever built.
“Used Korg Poly 800 ii. New power adapter. Missing battery cap on back, but not needed if using adapter. All keys in working order, all functioning. Makes some cool sounds, just didn’t work with the music I wanted to make.” 
” Used Korg Poly 800 ii. Still works great and makes some really cool sounds” 
“Another hidden treasure from uncle Freddie’s stash… It powers up and plays, not sure if all controls work- I’m not into synths/keyboards, but I did get some fun sounds through the headphone output! It needs a thorough cleaning and restoration/repair or is perfect for spare parts for your Delta. The joystick is broken off but is still functional, three slider knobs are missing, and the sliders and pots and could stand to be lubricated, tightened and/or replaced… Please note how some of the ink has been scratched off. This is being sold as-is. Shipping is being estimated at $125 due to final packaged size and weight, but I’ll happily refund the difference if the actual shipping charge is much less.”

“Got a Korg MS2000B up for grabs. The synth is in great condition and comes with its original power supply and vocoder mic. It has been used a bit, but only has one prominent scratch (pictured).”
“Good sounding synth! Easy to take anywhere. No issues with it, and decent cosmetic condition. This one’s missing the battery cover like most of them. You’ll just have to restore the default sounds when you put batteries back in it. You just have to play a sequence of noises into it that you can find on the internet…”

“Korg poly 800 analogue synthesizer keyboard. Very good condition. Just a few slight marks. Comes with hard case and user manual.
“I am selling this awesome analog-digital vintage synthesizer from the wonderful 1980s. This thing sounds retro and phat, but can also be used for nice thin “plucks” and “plinks”.
“This Korg 707 needs about half of the buttons on the control panel replaced. It works great as a sound module, programming patches over MIDI with editor software. Until the buttons are replaced though, you will not be patching on the unit itself. Things look fairly clean inside. ”

“I’m selling a classic 61-Key Korg Synth Workstation. See pictures for details, but it appears it was dropped by the previous owner. Still works great though. I’ve been using it to record some songs and I love it. Have had no problems with it at all. Lots of built in sounds, plus a sequencer so it’s a lot of fun to play around on. Perfect for anyone whether they’re looking to learn on it or a professional with a home studio looking to record or even play live.
