* semi-modular analogue synthesizer 
"This listing is for a vintage Moog Minimoog Model D analog synthesizer, serial number 1476, manufactured in 1972. This is an early Moog Music (Williamsville, NY) model with the following features:
"The introduction of the Hammond Novachord, the world's first polyphonic synthesizer, at the 1939 World's Fair is a major milestone in electronic keyboard musical instrument history. With over 100 vacuum tubes inside, this synthesizer has a thick, harmonically rich sound that you can't get elsewhere. The instrument is incredibly rare (only 500 are said to have ever been made, and who knows how many remain in existence). Commercial sample libraries of this instrument alone cost $300; that's how rare, complex, and musically useful this instrument is!
"Rare chance to buy a Switcheroo synthesizer in fantastic condition. Only a few of these were ever made by Health Club. 
Based on Ray Wilson's MFOS design this is quite a one-off synth. Of all the synths I have owned it reminds me most of a VCS3 in terms of the rawness of the sound and the endless possibilities to cross modulate everything. You can also do some unusual things such as plug in a guitar, keyboard, drum machine into the envelope follower and it can then modulate the VCA, oscillators, and filter! The Envelope can be triggered by a gate signal from a sequencer or keyboard or it can be triggered by the LFO or it can self loop (like the VCS3 trapezoid). Works great as a drone machinne, as well as a full fledged synth. The oscillators can be synced together and modulated by just about anything and everything. All in all a great synth for experimentation and research into the farthest corners of the sonic sphere (OK a bit OTT but you know what I mean). Includes 12vAC adapter."
"There are no cosmetic flaws on this unit, though I must disclose that the number pads that change the patches sometimes double when you tap them - and I think a tech who examined the unit may have left a small screw in the unit that rattles around if you pick up the keyboard and tip it. It is in perfect working order, the joystick and aftertouch both work!"
"Unique DIY built dual 4 step analog sequencer.
"Serge Modular double rack, custom designed by Sound Transform Systems when they were based in Oakland, California... Modulate away with countless CV and Gate ins and outs with open ended variations of patches to explore in countless combinations. Banana plug creativity by stacking and routing multiple outs to various filters, oscillators, wave modifiers and more. This modular is not the run of the mill modular but desgined to be very colorful , creative and exploratory in DEEP sound design. Its is not your typical 3 oscillators and a filter with a VCA but actually much more...
