Musitronics Mu-Tron Bi-Phase with C-100 Opti-Pot Pedal

Complete with the rare Opti-Pot controller. Serviced, calibrated and in full working order – sounds superb.

The condition is good with the usual signs of age. There are scratches, scrapes and dings to the case, but it’s built like a tank and nothing affects the operation. The knobs have some wear and the tops have been re-painted black to cover minor scratches. Click on the photos to zoom in and see more shots. The Opti-Pot pedal has been modified to offer greater sweep than the original (now sweeps as much as the pots on the unit) – very cool.

Freshly-serviced and calibrated by our tech – sounds spot on.

Converted to 240v (can be swapped back to 110v if needed). 

We love Bi-Phases (it’s in our top three phasers for sure) and we’re not alone: not only are they a staple effect of many dub reggae producers (Lee Perry most notably), but they’re widely-used with guitars/synths/keys etc in a wide variety of genres. A truly legendary effect.

We are big Mutron fans and usually have several other Musitronics pedals, including the Mu-tron III, Phasor, Phasor II and Octave Divider – see all our Mu-tron listings here

As used by the Smashing Pumpkins on Siamese Dream:

“This is one of the secrets to our secret sound. This is the Mutron Biphase. We run everything through it – everything. It’s fabulous” – Butch Vig

And of course, Lee Perry and many dub/reggae artists that have followed – hi-hats, guitars, keys all sound ‘proper’ through a Bi-Phase…
