BOSS XS-100 Poly Shifter

The BOSS XS-100 Poly Shifter: Next-Level Pitch Control with Full Polyphonic Precision

Flagship Polyphonic Pitch Shifting Pedal

The BOSS XS-100 Poly Shifter is the brand’s most advanced pitch-shifting effect to date, offering glitch-free polyphonic pitch transitions that preserve your tone’s integrity even when playing full chords or intricate lines. Whether you're sweeping octaves, detuning subtly, or retuning on the fly with drop/capo functionality, the XS-100 responds immediately and transparently. Guitarists and bassists alike will appreciate how this pedal maintains the natural character of their instrument with zero compromise.

Real-Time Expression and Control

This is no ordinary pitch shifter. The onboard expression pedal is smooth and responsive, delivering real-time control over pitch shifts across a range of up to four octaves. The toe-switch is user-assignable, letting you instantly toggle functions like one-octave jumps or effect bypass. A bright LCD screen offers real-time pitch feedback and intuitive menu navigation, making on-the-fly adjustments simple and efficient—even in dark stage environments.

Built for Modern Rigs

With MIDI I/O, USB-C for firmware updates, and assignable external control jacks, the XS-100 integrates effortlessly into complex pedalboards or studio setups. Use the dual footswitch layout to control both effect activation and pitch-shift range, while the analog dry-through ensures your original signal stays untouched. The expression pedal curve is adjustable for personalized response, and you can save and recall up to 30 custom presets, streamlining your stage setup.

Ideal for Guitar and Bass

Unlike many pitch-shifting pedals that struggle with low frequencies or aggressive playing techniques, the XS-100 supports full-range audio with remarkable fidelity. It’s equally at home with deep bass runs as it is with soaring lead guitar melodies. And thanks to its brand-new pitch algorithm and ultra-low latency, you can trust the XS-100 to stay in sync with your performance, no matter how demanding.

Road-Ready Design

Encased in a rugged, eye-catching chassis, the XS-100 is built for serious gigging. Whether you’re touring, recording, or exploring new soundscapes at home, this pedal is engineered for stability and reliability. Rubber-capped controls, durable switches, and metal construction ensure it can take whatever you throw at it, while continuing to deliver pristine pitch perfection every time.
