BOSS has announced the XS-100 and XS-1 Poly Shifter, two cutting-edge pitch-shifting pedals designed for guitar, bass, and beyond. Both models harness new-generation BOSS technology to deliver unmatched real-time pitch performance with natural tone, seamless response, and creative flexibility.
The XS-100 serves as a full-featured pitch-shifting workstation, offering an impressive eight-octave range, onboard expression control, and deep connectivity options for integrating into advanced setups. The XS-1, meanwhile, packs the core power of the XS-100 into the classic BOSS compact pedal format, making it a quick, portable solution for drop tunings, capo effects, octaves, and expressive bends using an optional expression pedal.
BOSS engineers developed the XS series using entirely new algorithms and a custom DSP platform, eliminating the artifacts that often plague pitch-based effects. The result is balanced, polyphonic performance that retains the natural attack and tonal character of your instrument, even during complex chord voicings and sustained leads. Every note feels smooth, musical, and authentically “you.”
XS-100 Poly Shifter
The XS-100 is a creative powerhouse built to transform how musicians approach pitch and performance.
Key highlights include:
- Massive Range: Shift pitch up or down across eight octaves with expressive real-time control.
- Dynamic Pedal Expression: A responsive onboard pedal delivers linear control, with customizable up/down speeds for fluid or mechanical-style sweeps.
- Toe-Switch Pitch Jumps: Trigger momentary shifts with adjustable range and timing for dramatic transitions.
- Advanced Control: Two onboard footswitches provide instant retuning in semitone steps, while additional external footswitches or an expression pedal expand possibilities further.
- MIDI Integration: Full MIDI I/O enables advanced setups, from remote control to synchronizing effects across a rig.
- 30 User Memories: Instantly recall performance-ready setups for live or studio use.
- Parallel Routing: A mirrored output allows flexible signal paths for complex rigs.
Whether you’re crafting cinematic swells or exploring new harmonic territory, the XS-100 gives you complete authority over your pitch domain.
XS-1 Poly Shifter
Compact, versatile, and performance-ready, the XS-1 delivers instant retuning and octave control in the iconic BOSS stompbox enclosure.
Key features include:
- Wide Tuning Range: Adjust pitch within ±7 semitones or shift up/down by three octaves.
- Blend Control: Use the Balance knob to mix dry and effected signals for everything from full retunes to lush 12-string tones.
- Detune Mode: Add depth with shimmering double-tracked effects and high-definition tone.
- Flexible Control Options: Assign the pedal switch for on/off or momentary operation, connect external footswitches for alternate tunings, or add an expression pedal for smooth pitch bends.
The XS-1 is ideal for players who need quick tuning changes, subtle harmonization, or bold, experimental sound design—all without breaking stride on stage.
