BOSS XS-100 Poly Shifter

The BOSS XS-100 Poly Shifter redefines what a pitch-shifting pedal can achieve, bringing cutting-edge technology and pristine tone to your signal chain. This powerhouse is fueled by new, proprietary BOSS algorithms and a dedicated high-speed DSP platform, delivering class-leading polyphonic tracking that feels entirely natural and musical. Unlike conventional pitch shifters that often introduce distracting digital artifacts, the XS-100’s advanced circuit preserves the fundamental character and attack of your instrument, even when handling complex chords or fast, sustained lead lines. This digital circuit masterclass is engineered for the modern guitarist and bassist who demands absolutely flawless performance and high-fidelity sound quality.

As a versatile expression machine, the XS-100 puts total pitch control directly under your foot. Glide effortlessly across an incredible eight-octave range using the ultra-smooth, integrated expression pedal to create dramatic glissandos, warbling textures, or motor-revving effects. Beyond creative sound sculpting, this pedal handles essential gig-day utility with unparalleled ease, offering fixed pitch settings for instant drop tunings, capo simulations, and rich doubling effects via its dedicated Detune mode.

As is standard for the legendary BOSS brand, the XS-100 features rugged, professional-grade construction. Built to withstand years of heavy use on the road and in the studio, this stage-ready enclosure is packed with flexible connectivity, including TRS MIDI I/O for advanced rig integration and external control. With 30 onboard memory slots, you can store and instantly recall your favorite setups for every song in your setlist.
