Here's a recently serviced 1970's Mutron I Phasor by Musitronics. A new 3 prong AC Cable was installed. Great working condition!
Mu-tron (short for Musictronics) developed a series of highly innovative effects throughout the '70s, including the popular Mu-Tron III envelope filter. The Mu-tron Phasor II was an upgraded version of the Mu-tron Phasor with feedback, depth and rate controls.
