“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.
” Here we have a Korg Poly 61 with issues, I have had this for a few years with the intention of fixing it. It lights up and makes sound but has suffered from a battery leak .
” Korg Poly-800-ll Polyphonic Vintage Analogue Synthesiser, well sort after priced to sell.”

“Vintage 1980’s Yamaha DX21 Synthesizer in used condition but still working fine.” 
” DX100 in good condition for age. Some scratches, as seen in pics, but nothing major – full working order” 
“Very good condition, one owner, mild use, smoke-free, and fully functional except the battery needs to be replaced. All buttons are functional and none have cracks from overuse. Because the battery is dead, I loaded sounds into the on-board memory to prove that it is working properly. If loading sound banks via MIDI, the battery is not needed. Battery replacement procedure is fairly straight-forward and can be found on YouTube. There are minor scuffs and scratches on the bottom but nothing serious. Cosmetically, this item is in really good condition. I’m selling only because I have to downsize.” 
“I discovered this from the original owner’s son about two years ago and to find something this old to be in such a highly preserved condition, is rare. The synth stayed in his home since it was new. His son wasn’t a musician so he had no need for it, so I purchased it. I am a pilot and loaded it in my airplane and flew it home. Every switch and dial works perfectly and the keyboard feels new, the ribbon controller works perfectly, the keyboard feels new, the aftertouch is flawless and the sound is magical. Yamaha clearly put all of their pride into these keyboards back in the day, as nothing in my studio has this build quality.” 
“Yamaha dx 100 digital synthesizer is in good working condition. It comes with the manual and original box.” 
“The Yamaha TG55 is a pressure and velocity sensitive 1U rack (16 voice multitimbral) sample based synthesizer, works” 
“This unit has hardly seen the light of day since it was last used in the 90s. It appears to reuire some sort of disk for loading tones an this auction does not include any sort of disk. I do not have the equipment or know how to test that every function of this unit is working, but all of the menus seem to function properly on the screen and I have no reason to believe that this has any defects. ”

” The Sequential Circuits Six-Trak Polyphonic Synthesizer may be labelled as a “beginner model” by the company, but the features and functionality make it a prime choice for any synth enthusiast. Built with 48 velocity-sensitive keys and the same Curtis circuitry found in the company’s more expensive models, the Six-Trak boasts six voice polyphony and six VCOs for solid lead, bass, and pad modeling. Throw in an expansive onboard sequencer and single knob for one parameter control to achieve a world of sound right out of the gate.
“Analoger Klassiker!
“ARP Quartet ,49 key all switches and controls appear to be in excellent condition Overall excellent condition ,the wooden case NOT INCLUDED . not tested but probably works perfect will need to rewire or replace the power wire very minor fix so being sold as is as found no returns.” 
“Great condition, never use it. I edited custom patches using Max/MSP so if you have ableton you can easily turn this into a very cool sound design tool. No time and moving out of my apartment so ditching the lesser used gear. The detune on this synth is unlike any ive ever used before, really cool harmonics are possible ” 
“Table top yellow effect or synthesizer box with guitar pedal type bypass switch.
“Octave-Plateau Cat Stick in good condition for its age. This is almost a modular synthesizer in itself, yet is for use with modular or CV synths to add expressive control and sort of patch in VCO and XY signals in new configurations. It creates beautiful, complex, and really unusual modulations as would be appreciated by a performing musician or sound designer or an odd noise collector. This one works yet shows expected signs of moderate use and slightly discolored plastic. These are extremely rare.” 
“Overall, the synth is in superb working condition. The front panel is very clean, with hardly a mark to be seen, just small blemishes. The aluminium side panels are really tidy with only minor marks. The back panel is very clean with only minor blemishes to the paintwork.
