Original Model D Minimoog

via this auction
"The Minimoog is a monophonic analog synthesizer, invented by Bill Hemsath and Robert Moog. Released in 1971 by the original Moog Music, it continued in production until 1984.

The Minimoog was designed in response to the use of synthesizers in rock and pop music. Large modular synthesizers were expensive, large, and delicate, and were not ideal for live performance; the Minimoog was designed to include the most important parts of a modular synthesizer in a compact package, without the need for patch cords. It later surpassed this original purpose, however, and became a distinctive and popular instrument in its own right. It remains in demand today, nearly four decades after its introduction, for its intuitive design and powerful bass and lead sounds.
