The BOSS Poly Shifter represents a significant leap in polyphonic pitch-shifting technology, offering glitch-free, ultra-fast tracking across a wide range of up to ±7 semitones or ±3 octaves. Powered by advanced proprietary algorithms and 24-bit Adaptive Focus conversion, the XS-1 maintains the natural character and attack of your instrument while delivering pristine pitch-shifted tones.
The intuitive control set includes a rotary Shift knob for precise interval selection, a Balance control for dry/wet blending, and a Detune mode for subtle pitch variations up to ±20 cents. Performance flexibility is enhanced with toggle or momentary footswitch operation, allowing for either sustained pitch changes or temporary bends. External connectivity via the CTL/EXP jack supports either a footswitch for instant preset recall or an expression pedal for real-time pitch sweeping.
Designed for live versatility, the XS-1 enables seamless key changes, drop tunings, and creative effects like octave doubling and pitch bends without the need for instrument swaps. Its compact, stage-ready design and natural polyphonic response make it an essential tool for guitarists and bassists seeking both practical tuning solutions and expanded sonic possibilities.
