1976 Moog System 55 Modular Synth

This is a this vintage 1976 Moog System 55 modular synthesizer. This complete unit (every module and keyboard) recently underwent an extensive $7,000+ service, and has been used less than 2 hours since. This particular 55 was owned by Keith Emerson, and was acquired from his good friend and personal synth tech, who has worked with Emerson both on the road and in the studio for over 30 years.

The reason for some modules being RA Moog, some being from ’73, and others dating from ’76-’77, is because as Emerson would service his monster Moog’s modules one at a time, he would swap between units. Although at one point this was an intact ’76/’77 System, it has since been serviced and repaired, as Emerson’s demanding touring schedule dictated.

Included are both original cabinets, (although the smaller top cabinet is in rough shape due to tour abuse), a reissue 22-space top cabinet, a reissue keyboard garage/stand, an original 950 RA Moog controller, and a variety of cables. Everything one needs to fully use this synth will be included. As explained, this synth works perfectly and sounds amazing.
