Boss XS-1 Compact Poly Shifter Guitar Pedal

The BOSS XS-1 Compact Poly Shifter is a powerful, polyphonic pitch-shifting pedal designed for guitarists and bassists who want instant, flexible tuning changes without switching instruments. Whether you need subtle detuning, realistic capo emulation, or dramatic octave jumps, the XS-1 delivers with stunning clarity and ultra-low latency.

Equipped with a brand-new pitch-shifting algorithm, the XS-1 tracks chords and fast runs with precision, preserving the natural tone and feel of your instrument. It handles drop tunings, octave layering, and pitch bends up to three octaves up or downall in a compact, pedalboard-friendly design. Use the BALANCE knob to blend dry and effected signals for thick harmonies or lush octave textures. With support for additional footswitches or an expression pedal, the XS-1 offers hands-free creative control, making it an essential tool for live performance, recording, or practice.
