The Electro Harmonix Stereo Polyphase resurrects the popular Polyphase pedal in the XO die cast series. Now in stereo and with an improved housing, the Stereo Polyphase gives you a LFO controlled phaser and Envelope Follower in one! Have you every wanted a phase tone but wihout the constant rate, hoop up an Expression pedal to control it yourself! The Envelope mode can give you classic auto wah sounds, thanks to the photocouplers inside, or a touch sensitive phaser. The same features and controls that so many guitarists loved and relied on to crank out lush, otherworldly tones are still inside, but with a few extra versatile add-ons!
Mode: Switches the effect between a LFO Driven Phaser, Envelope, and Expression controlled phaser.
Feedback: Controls the phaser feedback/resonance.
Gain: Adjusts the sensitivity in Envelope mode or Signal in LFO mode. Start and Stop controls help shape the range at the beginning and end of the wave.
Rate: Controls the speed of the phaser, in LFO mode only.
Toggle Switch: Controls the Attack speed in Env mode or between Sawtooth and Square Waves in Phaser mode.
