” This was a strange storage unit auction find in the midwest. I don’t know the story with the clear body, but I’ve never seen another one like it.
The roadcase it comes in is worn on the outside, but the foam inside is still good.
Here’s what’s been done to it:
~ All sliders were removed, cleaned, lubricated and reinstalled
~ All remaining controls were cleaned
~ The keyboard was completely disassembled, cleaned, rebushed, and all contacts were cleaned and adjusted
~ All tantalum power decoupling caps were replaced with electrolytic capacitors
~ The power supply board was re-capped and calibrated
~ The 4075 filter module was removed, recapped, and modified for increased cutoff frequency response
~ The original multicolored (now badly discolored) set of slider caps were replaced with a new, all white set. I’ll include the original slider caps for anyone interested.
~ Full calibration of all functions.” Click here to search for synths on eBay
” 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.
“Huge fat mono analog sound. They do not make them anymore all 4 filters in this thing. This sounds amazing due to things that need to get paid i am selling this.”
” Great analoge synthasizer! Fat sounds. In good condition. I only used it in my studio. Never took it out of my studio. Vintage sounds and more. Very creative. Enjoy!”

“If you know then you know . Amazing 303 filter , crazy sequencer, full analog fat sound . Look up online for this secret gem. There is a white face (v1) and a black face (v2) the major upgrade is a battery that dies on the white face version that requires fixing. This version fixed that issue and doesn’t need anything. No box but comes with original manual and power supply . Super well kept and no major scratches or marks on it . Output is clear, everything works . Custom future retro wood side panel not sold anywhere and spare metal replacement side ends . Super rare and super acid !”

“Another one I really want to keep. The first and maybe only moog I’ll ever own. Alas, money is tight. This sounds great and is 100% functional. Previously used on European tours by a notable musician. Requires a Euro voltage adapter to use (although I’m guessing you could wire it for the US if you didn’t want to go this route).”
