“Korg EX-800 Polyphonic Analog Synthesizer module from the 1980’s. This is a used piece of vintage equipment. Receives MIDI, plays notes, loads patches. See pictures, case has some scuffs and scratches but functions normally. Two keys stick somewhat, which is typical of these units (you can open it up and clean the button contacts, videos on YouTube on how to do it.)
Includes a non-original power supply and a duplicate cassette that has the stock EX-800 patches on it. This cassette is the same one you can see for sale on eBay. Unit has been restored to factory defaults.”

Doesn’t include the extension cord.”
“Yamaha CS-01 vintage analog synthesizer with case, strap, and Yamaha power supply. Item is in great shape and plays well. This is a great monosynth capable of very deep basslines. The model was reportedly used for basslines by Steely and Clevie of Jamaican dancehall fame. The synth has some slight discoloration/fading above the keyboard and some discoloring, scratches and paint chipped off (see final 2 photos) around the sides and back of the casing, but is otherwise in good shape for a vintage item. No battery leakage. Battery cover is included. Foam inside battery cover has darkened with age. Internal speaker works or synth can be connected to external amplifier. Carrying case is original and has some discoloration/staining probably rectified with a handwash. Strap ends are on the synth and the strap is included if you want to play it as a keytar.” 
“These units are in excellent condition with minor scratches and general wear as pictured.
“Amazing multi-timbal polyphonic analogue synth built in 1984 by Sequential Circuits, with MIDI, on board sequencer, arpeggiator and monophonic unison mode for nice thick sounds. If you’re looking at this listing you probably already know what it can do, but check out this post http://www.vintagesynth.com/sci/stk.php or have a look on YouTube for videos of it in action.

“Vintage Oberheim TVS-1A Two-Voice Analog Synthesizer in 100% Working Condition. Very well cared for with all original knobs with caps, all LEDs working, no sticky or dead keys, no dirty pots, no hum or crackling. There is one issue with the high “B” key being a bit higher than the row (please see pic). It does not affect function or playability. This TVS-1A will be meticulously packed with only new bubble-wrap in the first new box. Then, more new bubble-wrap inside the second new box. A 37″x30″x18″ double-walled box weighing in at 51 lbs. 4 oz. Includes two power cables, copy of the manual and schematics. Capable of deep analog saturation without losing clarity. The incredible sound one expects from vintage Oberheim SEM modules. In 1975, Oberheim created their first compact, programmable and polyphonic synthesizer by coupling two SEM modules to a 37-note keyboard and a simple analog sequencer. This was what became the Two Voice. Oberheim achieved a polyphonic sound not yet seen at the time by hard-wiring the two monophonic SEMs into the compact keyboard design. In 1976 Oberheim came out with another module, the Polyphonic Synthesizer Programmer. This could memorize the control voltages of many parameters for up to eight SEM modules. When these were added to the Two Voice in the form of the Mini-Sequencer, Oberheim finally had one of the earliest programmable and polyphonic instruments. Each voice has its own filter. The filter is unique and like no other, and apparently cannot be reproduced even by its own creator. The 8-step analog sequencer controls each voice/module independently allowing two independent sequences to be run simultaneously if desired. ”

” Roland Alpha Juno polyphonic analog synthesizer with the accompanying Pg 300 Programmer. Smoke free studio. The keyboard works well, I have never had any issue with it. There is some over all wear and slight discoloration on 3 of the keys (pictured above). The Pg 300 works great and provides real time midi control over a ton of parameters. The Pg 300 Programmer works with both keyboard and rack mount versions of the Alph Juno family. Includes original power cords for both. Alpha Juno serial # 721520, Pg 300 serial #620419.”

“Hi everyone. This a vintage Roland D-50 keyboard. I am the original owner and it has lived it’s entire life in a smoke free home. You’ll be hard pressed to find one in this condition. No problems, No non-functioning keys, or any other nonsense. Just simply a well kept instrument. I have all the original manuals, two rom cards, and all the information that came with it when it was purchased. It can be heard on many albums from the late 1980’s!! Back in the day, every big time artist had one of these on their keyboard racks. The pictures are taken in natural light. There’s barely even any dust between the buttons or keys! It was kept covered with a felt pad. The only thing to note is a small dent on the bottom (see green arrow). It will be well packed in bubble wrap to ensure a safe journey to you!! Thanks!! ”
“This was my backup 8080 and as such did not see any use. Never racked. I had a volume pot mod done to both my units to prevent the dreaded broken volume knob problem from occurring. The post is now reinforced and lowered by about 1mm compared to stock.”
“For sale is a Roland D-10 Multi Timbral Linear Synthesizer Music Keyboard. In used condition and shows signs of light scratches from normal use.

“Roland Promars Vintage Compuphonic Analog SynthesizerGreat condition, works well I’ve used it for making tracks multiple times all the modes and effects / VCO etc are working. This is a Vintage synth so if you’re looking for a brand new stuff that’s not for you, faders can be a bit rusty or capricious but overall I’ve not had any issues with it. Again I’m not an expert I have quite a few vintage synth and use them all casually so if you need a perfectly accurate diagnostic of the synth I cannot provide it. Visually on the bottom left you have some discoloration otherwise as you can see on the pictures it is pretty clean !”
