Aaron Newman and Mike Beigel founded musitronics and launched the popular Mu-Tron pedal series in 1972. In 1976-1977 musicians Lol Creme and Kevin Godley from 10CC developed a guitar sustainer, the Gizmotron. Musitronics became the Gizmotron manufacturer. The Gizmotron proved difficult to make and was temporamental in use. The Gizmotron used mechanical plastic parts but none of the Musitronics staff were experts in engineering plastics. For example they found that that units made during the winter wouldn't work properly in hot weather.
Musitronics didn't have enough money to produce both the Gizmotron and the Mu-Tron line, and the company directors decided to sell Musitronics to ARP, a synthesizer company (that was in the process of developing a doomed guitar synth called the Avatar). ARP was meant to pay royalties on the Mu-Tron line, but they folded before Newman and Biegel collected a cent. They became Gizmo Incorporated and continued to try market the Gizmotron, but then Newman had a heart attack and the project was wound up. Newman later worked as an insurance agent and Mike Beigel continues to work as an electronics designer and consultant.
