Musictronics, more familiarly known as Mu-Tron, was launched in 1972 in Rosemont, New Jersey by Mike Beigel and Aaron Newman from a somewhat accidental beginning. Beigel was an engineer at Guild working on a line of synthesizers for the synth boom of the 70's. His project was scrapped after Guild president Al Dronge was killed in an accident and replaced by someone with less interest in the guitar company making a foray into synthesis. With these orphaned ideas in tow, he and Newman began to simplify their synthesizer sounds into small effect boxes that set the psychedelic tone of the 70's. Mu-Tron's offerings were used extensively from everyone from Jerry Garcia and Lee "Scratch" Perry to a new wave of effect-laden guitar heroes like Kevin Shields and Billy Corgan.

Like so many great guitar-world experiments of the 70's, the Mu-Tron company was fairly short lived. After several years of cultural influence and colorful collaborations with the likes of Dan Armstrong, Mu-Tron struggled to keep afloat and sold out to legendary synth company ARP in 1978. Unfortunately, this led to the end of Mu-tron as ARP themselves went under in 1979. After long periods of trial, error, Gizmo, and inactivity, a revived Mu-Tron now offer more user-friendly, and much smaller footprint, reissues of their classic pedals thanks to the advent of modern pedal making technology.

This original earlier 1970s Mu-tron Phasor is a very cool but comparatively primitive phaser shifter with just two controls: speed and depth. The SPEED knob provides a full sweepable range of options while DEPTH is a 3-way selector offering low, medium, and high amount of depth to the phase. This remained Mu-Tron's simpler answer to the iconic Bi-Phase effect until the introduction of the Phasor II around 1976. That unit featured a third knob and a more tone sculpting options the original Phasor lacked. Still, this is a period classic and a nice example of the early Mu-Tron aesthetic.
Length is 9 in. (22.9 cm.), 5 1/8 in. (13 cm.) width, and 2 1/4 in. (5.7 cm.) high.

This pedal appears all original with the exception of one top mounting screw. There is some typical cosmetic damage attributed to just some honest playwear but the classic '70s graphics are largely undisturbed. The original two-prong cable is still intact, All knobs and switches are clean and fully functional, and the original CTS pot is dated to the 8th week of 1975. The pedal does emit some to-be-expected buzz, typical of an analog device of this age and nature, but offers a full and transportative trippy phased-out sound. A 1970's classic, solid but not including any original packaging. Overall Excellent - Condition.
