BOSS XS-100 Poly Shifter
The BOSS XS-100 Poly Shifter takes everything that made the XS-1 essential and pushes it to an entirely new level. With a huge four-octave range, built-in expression pedal, onboard memory, and deep connectivity, the XS-100 is the most powerful polyphonic pitch-shifter BOSS has ever made. Whether you’re looking for instant alternate tunings, smooth glissandos, layered harmonies, or bold experimental textures, this flagship pedal delivers pristine, low-latency performance while preserving the natural character of your guitar or bass.
Designed for both stage and studio, the XS-100 features 30 user presets, MIDI I/O, USB-C for updates, and flexible routing with analog dry-through. Its LCD interface and quick-edit controls make dialing in tunings, pitch bends, and effect parameters fast and intuitive, while the integrated expression pedal with toe-switch allows for real-time control of pitch sweeps and dynamics. From subtle detune to dramatic ±4-octave shifts, the XS-100 is built to inspire creativity and handle any performance scenario.
