The Mu-tron Bi-Phase is an iconic pedal from the ’70s, with a unique vactrol-based design and two independent sweep generators which could be coupled, each with individual rate controls and the option to choose square or sine waves. The pedal is quite rare nowadays, but if you’re looking for that sound (and you’re not an analog purist), the Audio Damage team got you covered with their latest plugin/app (and if you’re an iOS user, you can get if for free – see our giveaway below!).
According to Chris Randall, “PhaseThree is a detailed model of the MuTron Bi-Phase, with all the lovely sound of that unit (along with its foibles and quirks.) It is worth noting that, due to aging factors, no two Bi-Phase hardware units sound alike; we found the best and most tuneful one we could lay our hands on, bought it for a faintly ridiculous price, and took it apart to see what made it tick. Like you do.
The result is a painstaking digital copy of the original unit, down to the unique sweep of its LFOs. With the latest version, we have departed from the original and added 12-stage phasors in addition to the six-stage versions found in the hardware units. (We feel that 12-stage phasors have a more modern sound that people expect in a current phasor, and that the six-stage versions in the original were somewhat lacking to the modern palette.)”
Price and Availability
PhaseThree is a paid upgrade to the old PhaseTwo phasor. It is available for 32/64 Windows AAX, VST, and VST3, for macOS 64-bit AAX, AU, VST, and VST3 (for $39), and for iOS 32/64 AUv3 (for $3.99).
