This Moog Modular was hand delivered to Los Angeles by Bob Moog himself sometime in 1974. Bob personally drove this synthesizer across country from New York, so he could personally make sure everything was right upon delivery. Michael used this massive synth on countless studio sessions including all of his sessions with Michael Jackson. His Modular 55 was patched & programmed by Michael Boddicker for the synth parts on Billie Jean and Thriller. It was also used for Donna Summers tracks, Finger on the Trigger and State of Independence. It was also used in recording sessions on several Laura Branigan albums, including her featured track, Imagination, which was in the 1983 smash hit movie Flashdance. This Boddicker owned Model 55 was designed and largely built by Bob Moog himself and it is a beautiful instrument to behold. Operation of the Modular 55 is quite musician-friendly as it features very straight forward input and output jacks and all the knobs are clearly labeled.

Thee voltage-controlled oscillator modules produce stunning tones and this unit has rather stable tuning once it is up to temperature. The real legendary Moog sound comes from the 24 dB/oct lowpass filter (the 904A). To this day, no one has come close to improving upon the original Moog filter and its patented ladder design. Additional modules include VCAs, envelope generators, highpass filters, equalizers, noise generators, a sequencer, and utilitarian modules such as audio mixers, control voltage processors and power supplies. There is no dedicated LFO module, however. Instead, one of the VCO modules has a rate slow enough (0.1 Hz) that it can be used as an LFO instead of a sound source.
