Boss XS-100 Poly Shifter Pitch-shift Pedal

Instantly Expand Your Guitar’s Range

Rugged and stage-ready, the BOSS XS-100 Poly Shifter lets your guitar — or bass — do the work of three. With a single press or sweep of the expression pedal, the XS-100 allows you to change tuning, conjure shimmering textures, or add wild, octave-bending layers to your solos. With its intuitive layout, built-in LCD screen, and expansive memory bank, the XS-100 puts creativity at your fingertips, featuring controls to blend your signal and a range that spans up to 4-octave shifts in either direction. Whether you need to drop tune for one song or want to add an octave to your arpeggios, the XS-100 provides a crisp, clean signal thanks to its proprietary Adaptive Focus method technology and 24-bit converters. Many guitarists stomp on the XS-100 when one guitar isn’t enough, and with its impressive shift range and straightforward controls, your sound is sure to soar.

Road-ready Versatility

The XS-100 isn’t just a guitarist’s toy — it’s a gigging workhorse, ready to evolve with whatever you throw at it. The durable design, analog dry-through, and bass-ready processing make it equally suited for high-gain rock, intricate pop textures, or thunderous low-end shifts. Additionally, a built-in expression pedal delivers sweeping bends across a ±4-octave range, while dual switches let you instantly retune or engage capo-style effects on the fly. With 30 recallable memories, MIDI I/O, and a clear graphic LCD, dialing in and recalling your favorite setups is easy.

High fidelity conversion

Behind the scenes, the XS-100 relies on 24-bit converters with Roland and BOSS’s proprietary Adaptive Focus method (AF). This cutting-edge tech vastly improves the signal-to-noise ratio, delivering a cleaner tone and more detail in every note. The result is high-fidelity pitch shifting that sounds natural whether you’re detuning for a heavier riff or soaring into octave-stacked leads. Plus, side parameters let you shape how the pedal responds to your playing, while its natural voicing pairs perfectly with the rest of your effects chain.
