Musitronics Mu-Tron Bi-Phase with C-100 Opti-Pot Pedal - SN 01960

From Tony's studio collection. Lovely set complete with the rare Opti-Pot controller. Serviced, calibrated and in full working order - sounds superb.

The condition is excellent with the usual signs of age - has been in regular use since I bought it many, many years ago. 

Freshly-serviced and calibrated by our techs - sounds spot on.

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...
