The Boss XS-1 Poly Shifter is a compact polyphonic pitch-shifting pedal capable of shifting guitar or bass pitch across a range of seven semitones and three octaves in either direction. Features a Balance knob for wet/dry mix and a Detune mode for chorus-like doubling effects. Reviewed by Guitar World as delivering artifact-free polyphonic tracking suitable for live gigging. Suited for drop tuning, capo simulation, key changes, and polyphonic pitch-shifting without the tracking artifacts of older monophonic designs.
