XS-100 Poly Shifter

The XS-100 Poly Shifter brings polyphonic pitch shifting to Boss's pedal lineup, tracking all six strings simultaneously for chord-accurate pitch shifting. Where monophonic pitch shifters only track single notes, the XS-100 handles full chords.

Polyphonic tracking processes each string's pitch independently, enabling clean pitch shifting of complex chords without the artifacts that monophonic shifters produce on polyphonic input. Multiple interval options cover common musical intervals.

Shift interval, Fine tuning, Direct level, and Effect level controls. The polyphonic processing requires more computational power than monophonic shifting. Expression pedal input for real-time interval control.

For players who need pitch shifting on chords, not just single notes. The polyphonic capability makes it suitable for alternate tuning simulation, capo simulation, and harmonic enrichment of strummed passages.
