The
Electro-Harmonix Pitch Fork
is a compact, highly versatile polyphonic pitch shifter and harmony pedal. Capable of transposing your instrument's pitch across a massive +/- 3 octave range, it tracks cleanly whether you are playing lightning-fast single-note runs or full, complex chords.
Core Controls & Layout
Shift Knob: An 11-position rotary switch that sets the maximum transposition interval, ranging from a subtle detune (17 cents) through major 2nds, 4ths, 5ths, octaves, up to a full 3-octave shift or whammy dive/rise.
Mode Toggle (Up / Down / Dual): Selects whether the pitch shift goes upward, downward, or outputs two harmonized pitch shifts simultaneously in Dual Mode (e.g., combining a major 3rd up with a perfect 5th up, or an octave up with an octave down).
Blend Knob: Wet/dry mix control that lets you blend your pristine instrument signal with the pitch-shifted voice.
Latch / Momentary Switch: Controls how the footswitch behaves. Latch mode turns the effect on/off with a standard click, while Momentary mode engages the pitch shift only while you hold down the footswitch—ideal for instant, dramatic whammy-style drops or soaring octave bursts.
