Powered by advanced BOSS algorithms developed over years of innovation, this powerful pedal shifts overall pitch while preserving your instrument’s true tonal character. Expect lightning–fast tracking, crystal–clear response, and uncompromised sound quality — whether you’re shifting down for drop tunings, simulating a capo, or exploring dramatic octave jumps.

With its intuitive interface and versatile controls, the XS–1 makes tuning changes seamless on stage or in the studio. A Balance knob blends direct and effected signals for creative textures, while Detune mode delivers lush doubling effects.
