“Amazing multifaceted synthesizer. Rare with some estimates being only 1200 ever produced hand wired Electrocomp semi modular analog synth in working order. Sounds great as is but could probably use a service to make it tip top” 
“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).”

“Great Condition, i purchased it less than a year ago, it had just been serviced. Includes Japanese to US Converter….so it powers on and works great. I would describe the sliders as sticky. They feel tight……more so than the Roland Jupiter 6 that i had. I use a tuner on the oscillators……they are accurate for about….+-…2 octaves….”

Programmer is in fantastic, shiny condition and works perfectly, and comes with original case and programming cable.”
