Cascading phase shifting in stereo!

The Stereo Polyphase uses optocouplers to produce a smooth, liquidy tone that can elevate your playing out of this world. The Stereo Polyphase Feedback control gives you the ability to vary the sound of the phase shifter, so that you have the final say on the character of the phase shifter's tone. In ENV mode the Stereo Polyphase is a phase shifter controlled by an envelope follower. In LFO mode the Stereo Polyphase is a phase shifter controlled by a low-frequency oscillator. In EXP mode use an expression pedal (not included) to control the phase shifter. You may also use an expression pedal in LFO mode or in ENV mode to control the range of the phase shifter. Hook up the Stereo Polyphase in stereo (each output to a separate amp/mixer channel) for a broad stereo image.

Electro-Harmonix Stereo Polyphase Features:
  • User-determinable Start and Stop points for phase shifting
  • Expression pedal operation available (not included)
  • Operates in mono or stereo
