Professor’s Notes
The Pitch Fork is one of the Professor’s go-to tools for instant transformation—clean, quick, and beautifully flexible. It bends your signal up or down with crystalline precision, from subtle harmony to wild synth-like leaps. Smooth, stable, and endlessly creative, the Pitch Fork rewards curiosity. Choose an interval, adjust the blend, and suddenly your familiar lines take on a fresh identity—subtle or bold, always fun.

Description
The Electro-Harmonix Pitch Fork is a versatile polyphonic pitch shifter capable of shifting your signal up or down by up to three octaves, with flawless tracking and zero fuss. It can operate in up, down, or dual modes, allowing for harmonies, doubled intervals, or rich chordal textures.

A dedicated Blend knob lets you balance dry and shifted signals, while the Shift switch selects intervals ranging from minor seconds to multiple octaves. The Pitch Fork can also be driven with an expression pedal, giving you real-time control over sweeping pitch bends, dramatic dives, or evolving harmonies.

Whether you’re crafting organ-like layers, thickening riffs, creating bass lines from a guitar, or pushing into experimental sound design, the Pitch Fork keeps everything clean, stable, and musically responsive. Compact, rugged, and wildly creative—it’s a staple in both traditional and experimental rigs.
