BOSSXS-100 Poly Shifter Pedal - Blue
1/5
Independent shopping perspective
The Korena take
Built-in expression control makes the XS-100 a hands-on pitch shifter for guitar and bass. The pedal can sweep pitch four octaves up or down, with fixed settings covering the same range. Two assignable footswitches handle retuning, effect toggling, or momentary pitch changes, and 30 memories let you return to saved setups. A backlit LCD supports navigation, while MIDI I/O, analog dry-through, and buffered bypass provide connection options for more involved rigs.
Strong match
Who this is for
- Stage sets that need instant drop or capo-style retuning for individual songs.
- Players who want foot-controlled pitch sweeps, octave jumps, or momentary pitch changes.
- Guitar and bass rigs using saved pitch setups and MIDI control.
Consider the trade-offs
When to look elsewhere
- Players who need more than 30 stored setups.
- Users who need the USB-C connection for control or audio; it is for updates only.
