“The Korg Poly 61M, first of the Nobless synthesizers, is the same as the Poly61 but with a MIDI in/our port. This machine is in superb shape, with excellent circuit board, and all components are in full working order. The best way to see how amazing this instrument this is, is by watching a short tutorial on the two best selling points of this instrument- the arpeggiator and, of course, making programs that can be saved to memory. The biggest cosmetic defects are a ding in the back corner (visible in the power-cable photo, and some spray paint dots on the left side).
Purchase includes:
-Korg Poly 61M synthesizer
-A bound copy of the manual
– quarter-inch male-male cable
-18-foot eighth-inch female-male extender cable
– eighth-inch male-females splitter
-eighth inch to quarter-inch adapter
-Apple earbuds (the nice $30 ones)”

“This is a Korg Polysix 6-voice synth from 1981. Everything is tested and works great. I built a new clone programmer board for it since the old one had some battery leak damage. The new board is a clone, functionally identical to the original. No new or changed functions. This board has the memory and knob scanner circuits. There is no audio path on this board.

“• Korg MS200 Analog Modeling Synthesizer
“This is a rare and wonderful vintage piece that needs a little TLC. These are known to have capacitors that leak oil and erode the circuit, but this one has had *all capacitors replaced* in 2012 and traces repaired. (note: if you find one of these with original capacitors, it’s a matter of time before those capacitors cause a meltdown.)

“Up for auction is a Korg Vc 10 Vc10 Analog Vocoder With Microphone. This item is tested/ working. The microphone that is included in this auction is not the original microphone, but it works great. As far as issues go, The left part of the plastic siding is chipped, and some of the screws are missing on the right portion of the plastic siding. When you pick up the vocoder it sounds like something is loose inside of it, but it does not affect the functionality. I hate to see this guy go but financial circumstances are forcing me to sell it. I will ship this item via Fedex and they will pack it/ ship it. No international bidders, Paypal only, and no returns.”
“Working, but needs a battery if you want the back-light illuminated. You can see the digital readout regardless, but it’s not as easy to see at a glance. The “E” key (13th white key from the right) sits slightly lower than the rest, but it still works fine. It is not a dead key. It probably needs cleaned or a return spring replaced. There are some scratches on the case and keys as you can see in the pictures. The steel case is solid with no dents or dings. Synth has some really amazing famous and classic sounds. ”
