When it comes to pitch shifting, the Boss XS-100 Poly Shifter is a game-changer. Born from years of BOSS innovation, this expression machine delivers studio-quality pitch effects with a natural feel and stunning clarity. Whether you're adding subtle detuning, diving four octaves down (or up), or creating complex harmonies on the fly, the XS-100 gives you the power to bend reality without breaking your sound.
Unleashing Limitless Creativity
This isn't just about tweaking your tone — it's about transforming your performance. The XS-100 is your secret weapon for everything from instant drop tunings and capo effects to wild, expressive pitch glides that will leave your audience speechless. Forget glitchy artifacts and unnatural tones; this is polyphonic pitch shifting as it was always meant to be - natural.
Pristine Pitch Shifting: Powered by brand-new BOSS algorithms and a high-performance DSP, the XS-100 delivers flawless polyphonic tracking. It preserves your guitar's core character, ensuring that even complex chords and soaring leads are reproduced with breathtaking clarity.
Total Expressive Control: The ultra-smooth onboard pedal provides linear control over a massive four-octave range. Glide seamlessly between notes or use the integrated toe switch to trigger dramatic, momentary pitch jumps for added dynamics.
On-the-Fly Tuning: Two dedicated footswitches let you instantly retune your instrument with fixed semitone steps. Go from standard tuning to Drop D, simulate a capo, or create otherworldly sounds with a single stomp.
Save Your Signature Sounds: Why dial in the perfect sound more than once? The XS-100 features 30 onboard memory slots, allowing you to save and recall your favorite custom setups instantly during a live set.
Redefine Your Sound with Precision and Personality
The XS-100 puts a universe of pitch-based effects at your feet, giving you complete control to sculpt your sound. It’s a creative powerhouse built for players who refuse to compromise.
Detune for Rich Doubling: Thicken up your sound with the detune function, which adds a subtle +/- 50 cent shift. It’s perfect for creating lush, chorus-like textures or wide, doubled-up rhythm tones that fill the room.
Customize Your Response: Tailor the pedal’s performance to match your playing style. Adjust the response curve for a feel that’s perfectly suited to you and customize the range to fit specific songs or techniques.
Reassignable Switches: Make the pedal work for you by freely reassigning the toe switch and footswitches to alternate functions. Whether you need momentary pitch changes or instant retuning, your ideal setup is just a few clicks away.
Built for the Stage, Ready for the Studio
Packed with flexible connectivity, the XS-100 is designed to integrate seamlessly into any rig, from a simple pedalboard to a complex MIDI-controlled setup.
Expanded Control Options: Don’t feel limited by what’s on the board. Connect up to two external footswitches or an expression pedal to unlock even more real-time control possibilities.
Full MIDI Integration: TRS MIDI I/O opens up a world of advanced applications. Control the XS-100 from an external MIDI device or use the pedal and footswitches to send MIDI commands to other gear in your rig.
Parallel Routing Flexibility: A dedicated secondary output mirrors the input signal, giving you the flexibility to create sophisticated parallel signal chains without needing extra splitter boxes.
The Ultimate Pitch-Shifting Workstation
The Boss XS-100 Poly Shifter is more than just an effect; it's an instrument in its own right. It offers the surgical precision needed for studio work and the rugged reliability required for the road. If you're ready to explore new sonic territories and take complete command of your pitch, your search ends here.
