Boss XS-1 Poly Shifter

Boss XS-1 Poly Shifter – Pitch Shifter/effect pedal for changing pitch, designed to provide instant and smooth tuning changes directly from the pedalboard. With a range of ±7 semitones and up to 3 octaves up or down, it allows for authentic performances of pieces in dropped tunings, quick transpositions to other keys, or the creation of unique and rich sound effects. 

The intuitive interface includes a Balance potentiometer for mixing between the direct sound and the effected sound, offering everything from complete retuning to 12-string guitar sounds or guitar/bass combinations. The Detune mode adds expressive doubling effects, with a clear and defined tone.
