Boss XS-1 Poly Shifter Pitch-shift Pedal

The BOSS XS-1 Poly Shifter brings advanced polyphonic pitch-shifting technology to a compact and rugged stompbox. Designed for guitar and bass, it delivers smooth, natural pitch changes while maintaining the original character, attack and playing response of your instrument.

With a massive six-octave pitch range, the XS-1 makes it easy to explore instant drop tunings, capo-style pitch changes, octave effects, harmonized sounds and subtle detuning. Its advanced algorithm provides clear, glitch-free tracking even when playing full chords or fast melodic passages.

The XS-1 also supports external footswitch and expression pedal control, giving players additional flexibility for switching between tunings or creating real-time pitch-bending effects.
