Up for Sale is a
Vintage 1970's Phase Shifter w / Original Switch Pedal! Made In USA!
This is really cool. You are looking at the Holy Grail of effects. This is a Vintage 1970's Musitronics Mu-Tron Bi-Phase w/ Original Switch Pedal. The Mutron Biphase is a legendary phasor pedal, designed by Mike Beigel along with Aaron Newman at Musitronics USA in about 1973-1974.
Phaser effects were common in the 1970s, but the Mutron Bi-Phase combined two phase shifting circuits and in its time was the preferred “the phaser-lover's 'phasor'”. It used technology from the old Uni-Vibe, with lamps and photo cells, and featuring two independent sweep generators which could be coupled, each with individual rate controls and the option to choose square or sine waves. One of the most, if not the most lush vintage pedals in existence.
Notable Users are Stevie Wonder, Frank Zappa, Jerry Garcia and many more. Everybody who was Anybody used these back in the 1970's. Unfortunately the company was mismanaged and went out of business in 1978. There are not a whole lot of these out there especially ones that have been fully serviced. Our Tech went through this unit and gave it a very thorough service. WORKING CONDITION: Excellent. Phenomenal. Stellar. This unit brings its unique phasing in wonderful clarity despite its external dings. Everything works and sounds wonderful, and masterfully gives you everything from slow, sweeping grandeur to busy, rapid pulses, and everything in between. Get the phaser everyone else wants theirs to sound like.

Cosmetics: Good "Relic" Condition. There are scratches, dings and dents on the metal housing. Everything functions and is in good working order. All the Street Cred! The wear is what gives this Mu-tron it's charm. Dripping with "Mojo" It is used. Not perfect. Look at the pictures closely. They will tell the story.
