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

Serviced, calibrated converted to 240v and in full working order – sounds superb. Complete with the rare Opti-pot pedal that really releases the full potential of what is without doubt one of the greatest phasers of all time (it’s in our top three for sure).

The condition is very good with the usual signs of age. There are some scratches, scrapes and dings to the case and knobs, but overall it presents very well. Click on the photos to zoom in and see more shots.

Freshly-serviced and calibrated by our tech who has worked on many of these pedals – this one sounds stunning.

Has been converted to 240v.

We love Bi-Phases 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…
