Electro-Harmonix Pitch Fork+: A Dual-Engine Polyphonic Pitch Powerhouse

The Electro-Harmonix Pitch Fork+ is a dual-engine polyphonic pitch shifter and harmonizer that expands the original Pitch Fork into a deep, programmable instrument. Two independent pitch-shift engines run at once, each covering a full three octaves up or down with fine detune, so you can generate rich harmonies and octave stacks from a single note or chord. Add 100 saveable programs, flexible Main and Aux outputs, and cross-modulation, and this pedal moves from simple octaves into genuine sound design. It is the flagship of the Pitch Fork line, built for players who want maximum pitch control under their feet.

Two Engines Working Together

The defining feature of the Pitch Fork+ is its pair of independent pitch-shift engines, each with its own interval and detune setting. Running two shifts simultaneously lets you build three-part harmonies, wide octave spreads, or a shimmering detuned double from one input. Because the engines can be routed separately to the Main and Aux outputs, you can send each pitched voice to a different amp or channel for a huge stereo image. This dual-engine architecture is what separates the Plus from the single-shift original.

Polyphonic Pitch Shifting Explained

Polyphonic pitch shifting means the pedal can raise or lower the pitch of an entire chord while keeping every note distinct and in tune. Older monophonic shifters could only track one note cleanly, but EHX's polyphonic engine analyzes the full signal so strummed chords transpose without warbling or glitching. This is why the Pitch Fork+ can turn a guitar into a twelve-string, a baritone, or a harmonized section rather than just an octave box. Understanding this lets you use it for full-chord parts, not only single-note leads.

Detune, Harmony, and Three-Octave Range

Each engine shifts from a subtle detune of a few cents all the way to three octaves in either direction. Small detune amounts thicken your tone into a chorused, twelve-string-like double, while precise interval settings create musical harmonies such as thirds, fifths, and octaves. Pushing to the extremes yields deep sub-octaves for bass-like weight or soaring high voices for synth-style leads. This range makes one pedal capable of thickening, harmonizing, and radically transposing your sound.

X-MOD and Creative Sound Design

The Pitch Fork+ includes an X-MOD mode that cross-modulates its two engines, feeding one into the other to produce FM and ring-modulator-style textures. This turns the pedal from a clean harmonizer into a source of metallic, bell-like, and dissonant tones normally associated with modular synthesis. Combined with expression control over the shift amount, X-MOD becomes a performance tool for glitchy dives and evolving effects. It is the feature that lets adventurous players push far beyond conventional pitch shifting.

Programs, Expression, and Footswitch Control

The pedal stores 100 user programs alongside 10 factory presets, so every harmony, detune, or effect you create can be recalled instantly. An expression input controls pitch, glissando, or volume in real time, while an EXT input accepts an external foot controller for hands-free preset changes and momentary dives. The programmable User footswitch adds latch and momentary behaviors tailored to your set. Together these make the Pitch Fork+ a fully gig-ready, preset-driven pitch station.

Who the Pitch Fork+ Is For

The Pitch Fork+ suits gigging guitarists who need dependable harmonies and octaves, experimental players chasing FM and ring-mod textures, and anyone who found the original Pitch Fork too limited. Its dual engines, deep presets, and expression control make it a do-everything pitch instrument rather than a single-trick box. If you want twelve-string shimmer, whammy dives, three-part harmony, and synth-like modulation in one enclosure, this flagship covers all of it. It is the most capable pitch shifter EHX puts under a single footswitch layout.
