The Mu-Tron Bi-Phase is a dual phase-shifter invented and marketed by Musictronics USA in the 70s. It has become well-known and well-loved for it’s ‘classic’ warm and deep sound, as well as the flexibility of it’s control and audio-processing capabilities. The all analog Bi-Phase II recreates the creamy HiFi phase of the mythical Musitronics Bi-Phase pedal and packs into a compact, pedal board friendly package. The Bi Phase II is designed to fit into modern day pedal chain as it may be powered by standard power bricks, routes the signal from right to left to allow for easy patching, and an interface which is much more symmetrical and intuitive than the original. In addition to the new OptoMod Phase-Light technology, the Bi-Phase II adds 4 stage mode with a fixed feedback to get the classic rock tones that work well with overdrive and distortion harmonics. Finally, there is a control voltage input that will allow for real-time control of Rate or Depth to give the musician utmost expression and “Leslie Speaker” type of sounds. The pedal also supports control voltage out so that 2 or more Bi-Phase II pedals can be linked to offer QuadPhase and DualBiPhase types of applications.
