BOSSXS-1 Poly Shifter Pedal - Blue
1/4
Independent shopping perspective
The Korena take
The XS-1 combines alternate-tuning, harmony, octave, and detune functions in a compact pedal. Its shift range reaches seven semitones or up to three octaves in either direction, while the Balance control mixes dry and shifted sound. Shift and Mode switches select up, down, or detune operation. An expression pedal can add real-time pitch sweeps, and external footswitches can recall up to three custom setups or provide momentary control during a song.
Strong match
Who this is for
- Live sets that require alternate tuning or pitch changes during a song.
- Guitar or bass parts using harmonized lines, octave layers, or detune movement.
Consider the trade-offs
When to look elsewhere
- Players who need an external footswitch included; it is sold separately.
- Rigs that require true bypass; the XS-1 uses buffered bypass.
