"Up for auction is a Vintage Moog Sonic Six synthesizer. It has been thoroughly cleaned and checked and is in perfect working order. This is an absolutely unique item with a very interesting history. This is the last brand new Moog synthesizer in existence, the last new Moog to leave the factory, and the last Moog Sonic Six synthesizer ever produced.

When Moog ceased operations in 1993, Tim Smith and Dave Weyer , on a tip from Tom Rhea, purchased the remaining inventory from the Moog factory and had it shipped to Montana. The inventory consisted of one completed Sonic Six unit , three that had failed quality control , owner and service manuals ( I will make a copy and include these ) , some circuit boards and power supplys for various models including the MemoryMoog , MultiMoog , PolyMoog , and several boxes of miscellaneous parts. Moog stopped production of the Sonic Six in 1979. The Sonic Sx listed here , the last completed unit , sat on the production line until 1993, and after leaving was kept in Tim Smith's warehouse until his passing in 2001.

Tim Smith was the Western Regional Tech Rep for Sequential Circuits , Arp, Moog and also contributed to the famous Vintage Synthesizers book and articles in Keyboard Magazine. Tim was an expert at repairing all kinds of synthesizers and electronics and over the years became friends with many notable synth designers and gurus ; Bob Moog , Tom Rhea , John Simonton , and Stanley Jugleib to name a few. Dave Weyer is more well known as the amp guru at West Coast Organ and Amp in Hollywood California . His amplifier mods and repaiirs were enjoyed by many well known musicians including Neil Young, John Lennon, and Jimi Hendrix. Tim and Dave also happened to purchase the remaining inventory of Arp and ElectroComp the same year..."
