Mu-Tron Phasor III

Reviving the wonderful sound of the opto-phaser Phasor II with parts of the Bi-Phase comes Mu-Tron's Phasor III, a fully analog phaser with several options for expressive modulation. Phasor III offers two phaser flavors: a 4-stage option that has a set feedback amount to recreate the classic rock 'n roll tones, and the 6-stage with a variable feedback amount. Sweep through frequencies with the rate and depth controls to add either a sine or square wave for modulation—the modulation shape is determined by the Shape switch.

Additionally, controlling your Phasor III from external sources is simple with the CV input, perfect for sending Expression or control voltage signals to sweep the depth or rate of modulation. This CV can be daisy chained to other pedals or even more Phasor IIIs with the CV output. Recreate textbook modulation sound palettes or explore new ones with the Phasor III from Mu-Tron.
