Boss XS-1 Poly Shifter

Instant Tuning, Flawless Sound

XS-1 Poly Shifter offers instant tuning capabilities in a compact body. Thanks to advanced algorithms developed by BOSS over many years, this "magic" pedal shifts the pitch while completely preserving the true character of your instrument.

Whether you are dropping the tuning, creating a capo effect, or performing sharp octave jumps for effect — you will always get fast tracking, crystal-clear response, and zero tone loss. The versatile XS-1 makes tuning changes fast, fluid, and seamless, creating a new level of freedom in your performance.
