Mu-Tron Bi-Phase clone
This is a clone of the old Mu-Tron Bi-Phase. It's two six-stage optical phasers that can be used independently or in unison. If you use them together, there are some special methods for combining them.
Essentially what you have here are two flashing LEDs, each surrounded by six photoresistors that translate the flashing light to phase differential. In the standard mode the Rate knobs control how fast each LED (left and right) flashes.
If you turn on the LFO Synch switch, both LEDs will flash at exactly the same rate. This essentially gives you a 12-stage phaser instead of two 6-stage phasers.
If you turn on the LFO Invert switch, the two LEDs will flash at the opposite time. When one is dark, the other is fully illuminated. This gives you two 6-stage phasers in diametric opposition to each other with a kind of unusual crossover point where both LEDs are momentarily at the same level of illumination.
It's a very interesting and fun circuit that yields some amazingly chewy phasing sounds.
