Boss XS-1 Poly Shifter Effect Pedal

XS-1 Poly Shifter Effect Pedal Item Description

The XS-1 Poly Shifter delivers instant retuning in a convenient, compact footprint. Driven by advanced BOSS algorithms years in the making, this magical pedal transforms the overall pitch while maintaining your instrument’s true character. You get speedy tracking, crystal-clear response, and zero compromise in tone—whether shifting down, simulating a capo, or using extreme octave jumps for effect. The versatile XS-1 unlocks a new level of performance freedom, making tuning changes fast, fluid, and seamless.

In developing the XS series, BOSS engineers pioneered new methods to advance real-time pitch shifting and eliminate the tonal artifacts common in conventional designs. Powered by finely tuned algorithms and a specially selected DSP platform, the XS-1 provides balanced polyphonic performance that feels natural and musical across all playing styles, pickup positions, and pedal setups. Your instrument’s attack and tonal character are fully preserved, and even complex chords and sustained lead tones—typically a challenge for pitch shifters—are reproduced with stunning clarity.

Retuning during a performance means long pauses, instrument swaps, or pedal solutions that can color the sound in undesirable ways. With the XS-1, you can shift tunings on demand and retain great sound, feel, and response—without ever breaking the momentum of a show. Authentically play songs in drop tunings, change keys to suit a vocalist’s range, create unique extended-range sounds, and more.
