Musitronics Mu-Tron Bi-Phase

Excellent condition. Serviced, calibrated and in full working order – sounds superb. Has a custom switch.

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

The custom switch came with it. It has switches to turn each of the phasers off and on (like the standard double foot switch), plus it has a bypass switch and a pot to control the wet/dry mix (this control is not great to be honest but doesn’t affect the unit adversely so we left it).

Also has a mod on the rear with additional in and out to each phaser on RCA/phone sockets. These do not affect the normal operation of the unit.

120v unit, can have a new transformer fitted to convert it to 240v if required – the cost of this is £60 including VAT.

CONDITION: Excellent, especially for one of these. Has minor scratches, scrapes and dings to the case but nothing serious. Click on the photos to zoom in and see more shots.

For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way.

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..
