XS-1
$199.99Reference price
The XS-1 is a BOSS pitch shifter pedal that changes the pitch of a guitar or bass in an instant. A newly developed advanced algorithm delivers natural pitch shifting that preserves the instrument's character and playing feel, free from response changes and glitches. Alongside semitone pitch changes and octave up and down, the DETUNE function opens up further expressive options.
A pitch shifter that switches pitch instantly without changing the playing feel
A compact pedal in the XS series built around a newly developed algorithm. It was designed to produce natural-sounding pitch shifting on complex chords and long sustained leads, regardless of playing style, pickups, or the gear it is paired with.
Tuning changes on stage
Pitch can be changed with a single press of the pedal, with no need to stop playing and retune. It handles songs in down-tunings and key changes to match a vocalist's range without altering the playing feel.
A range of plus or minus 7 semitones and 3 octaves
The BALANCE knob adjusts the mix of direct and effect sound; blending in the direct signal creates 12-string-like textures or the sound of guitar and bass playing together. The DETUNE switch adds a plus or minus 20-cent offset for a doubling effect.
Switch behavior to match the performance
The pedal switch can be set to toggle or momentary operation, suiting both song-length pitch changes and momentary accents in a solo. An optional footswitch connected to the CTL jack switches between up to three settings, and an expression pedal enables real-time pitch control.
