XS-100 4-in-1 Poly Shifter
The Boss XS-100 Poly Shifter is an advanced pitch-shifting workstation designed for guitarists and bassists, offering total pitch control across an impressive eight-octave range. Utilizing new BOSS algorithms, it delivers class-leading pitch shifting quality with a clear, natural response that preserves the instrument's fundamental sound character.

It includes fixed pitch settings for effects like drop tunings and capo simulations, and a Detune function (+/- 50 cents) for rich doubling effects. The XS-100 has fully customizable footswitches for momentary pitch changes, 30 memories for storing setups, MIDI I/O, and a dedicated analog output that mirrors the input signal. It functions as the ultimate pitch-shifting tool, offering versatility for subtle detuning or full-on pitch chaos.
