Boss XS-100 Poly Shifter

The BOSS XS-100 Poly Shifter sets a new benchmark in polyphonic pitch-shifting effects. This groundbreaking flagship pedal delivers ultimate flexibility and matchless audio quality while maintaining the instrument’s natural feeling in tone. Leveraging state-of-the-art technology, this Poly Shifter enables musicians to perform with unparalleled fluidity and precision, from wild octave sweeps to subtle detuning. With boundless creative potential, the XS-100 provides seamless pitch gliding combined with instant drop/capo retune features, and much more.
The XS-100 allows you to tune and adjust the pitch of your tone from -4 to +4 octaves, including every semitone in between. This ensures incredible accuracy, transient transparency, and clarity across all strings. It features the most advanced algorithm for retuning and pitch-shifting your instrument.

Use the two footswitches to independently control both the overall tuning and the pitch shift effect. The pitch shift effect is linked to the expression pedal, enabling precise real-time adjustments. There is an additional toe switch that activates when the expression pedal is fully engaged in the toe position. It can be set to latch or unlatch and assigned to various parameters. Both the switches and the expression pedal are fully customisable.
You can save all complex settings and assignments in 30 user memories, which can be browsed manually or recalled via MIDI.
The Analog Dry Through output delivers the direct input signal, unaffected by any effects, enabling you to process and mix it separately.
