This is the Prophecy Sounds Bi phase clone. From manufacturers info:
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 Prophecysound Pi-Phase seeks to accurately reproduce the sound and control layout of the original unit. Design goals for this reproduction of the Bi-Phase were:
to match, as closely as possible, the sound of the originalto maintain the same or a very similar control layoutto package the pedal in a size and format that would allow it to be used liveto dispense with the need for a special controller pedal for switching channels on/off, or for controlling pedal sweepThe Pi-Phase is all-analog and parts-accurate to the original, as much as is possible. To our ears, and the ears of many previous customers, the Pi-Phase sounds like the real-deal. How much like it? Original Bi-Phases are pretty old, and some units suffer from parts drift, lack of maintenance, and lack of calibration; each 'well-gigged' Bi-Phase can easily sound different to the next. With the Pi-Phase we give you 'factory fresh' dual-phaser experience.
