BOSS XS-100 Poly Shifter - Unrivaled Dynamic Pitch Expression
If you have ever wished you could jump to a drop tuning, match a singer's key, or add dramatic pitch movement without changing guitars, the BOSS XS-100 is built for you. This is not a one-trick shifter - it is a full pitch workstation designed to feel natural under your hands and powerful under your feet.
Features (What it does)
- Advanced polyphonic pitch shifting with clear response and a natural feel that preserves your attack and tone.
- Eight-octave range for fixed semitone pitch settings - perfect for drop tunings, capo-style shifts, and creative sound design.
- Onboard expression pedal with toe switch for smooth, linear control across +/- four octaves and programmable momentary pitch jumps.
- Detune (+/- 50 cents) for rich doubling and widening effects.
- 30 onboard memories for instant recall of your favorite setups.
- Deep customization including adjustable pedal curve and response to match your playing style.
- Serious connectivity: analog THRU output that mirrors your input signal, external control support, TRS MIDI I/O, and USB for system updates.
Advantages (Why these features stand out)
- Stay in the moment live - keep the guitar you love in your hands while switching tunings and effects between songs.
- Dial in feel, not just sound - tailor the pedal response so pitch moves the way your foot naturally wants to move.
- Performance-ready control - use the toe switch and footswitch functions for instant, musical pitch hits and fast retunes.
- Rig-friendly routing - the dedicated THRU output makes parallel setups and advanced routing much easier.
Benefits (How it helps you make music)
- Play more songs with one guitar - cover drop-tuned setlists, alt tunings, and key changes without swapping instruments.
- Make solos pop - hit bold pitch jumps on command, or glide into new octaves with the expression pedal.
- Thicken your sound instantly - add detune doubling for width that still feels like "your" tone.
- Save time and stress - store 30 go-to presets and recall them in seconds.
