Boss XS-1 Poly Shifter

The Boss XS-1 is the BOSS pitch shifter pedal designed for those seeking natural and versatile sound without compromise. Thanks to advanced technology developed with proprietary algorithms and a dedicated DSP platform, the XS-1 delivers precise and musical polyphonic performance in any context. Unlike traditional pitch shifters, the XS-1 pedal preserves the attack and character of the instrument, keeping the tonal personality of the guitar or bass intact even during complex chords or sustained melody lines.

The BOSS XS-1 effect offers a range of transposition from +/- seven semitones up to three octaves up or down, covering virtually every musical need. The compact interface typical of BOSS pedals ensures simple and immediate controls, allowing you to quickly find the right setting. The Boss XS-1 lets you adjust the Balance to avoid pitch conflicts in semitones, or blend the direct signal in octave shifts for effects like 12-string guitar or guitar/bass combinations. Detune mode, on the other hand, enriches the sonic palette with realistic voiceovers and unique nuances.
