The Electro-Harmonix Stereo Polyphase Effects Pedal resurrects the popular Polyphase pedal as part of the Electro-Harmonix XO
die-cast series.

Now in stereo and an improved housing, the Stereo Polyphase Effects Pedal features the same features and controls that so many
guitarists loved and relied on to crank out lush, otherworldly tones from the original.

Featuring envelope/sweep switch, feedback level, rate, envelope sensitivity, envelope modulation, and modulation rate.
