Here is a vintage 1974 Musitronics Mu-Tron III electric guitar effects pedal in the original box with the original Musitronics PS-1 power supply! Perhaps the most famous of the excellent Musitronics product line, the Mu-Tron III was an instant success when originally made in the 1970s, and has remained consistently popular to the degree that is was faithfully reissued several times. The Mu-Tron III is an incredible sounding envelope filter/follower effect which has become an integral component of all bass players’ pedal boards, in addition to, a great effect for guitar, keyboard, and synth.
This particular example, serial number 08595, is in extremely excellent condition and is about as nice as they come. The box exhibits expected storage wear, and has since been reinforced with duct tape.
