Natural Sound with Advanced BOSS Technology
In developing the XS series, BOSS engineers pioneered new methods to advance real-time pitch shifting and eliminate tonal artifacts common in conventional designs. Powered by finely tuned algorithms and a specially selected DSP platform, the XS-100 delivers balanced polyphonic performance that sounds natural and musical in all playing styles, pickup positions, and pedal configurations. The attack and tonal character of your instrument are fully preserved, and even complex chords and sustained lead tones—typically a challenge for pitch shifters—are reproduced with stunning clarity.
Total Pitch Control
With the XS-100 under your foot, you command almost every imaginable pitch effect. The responsive pedal provides linear control of four octaves up or down, and independent pitch-shift speeds for each pedal direction make it easy to produce engine-revving tones and other interesting effects. At the end of the pedal stroke, you can use the integrated toe switch to introduce momentary pitch jumps with adjustable range and rise/fall time. Two footswitches are also available for bypassing the pedal shift and quickly retuning your instrument to fixed semitone steps over eight octaves.
Customize and Save
The XS-100 gives you the tools to shape pitch effects with precision and personality. Customize the pedal range for different songs or techniques and fine-tune the response curve to suit your playing style. Freely reassign the toe switch and footswitches to alternative functions. Create rich doubling effects with the detune option and explore many other ways to refine your sound. Once everything is dialed in, save your configuration into one of 30 memories for instant recall during live sets or studio sessions.
Integrate into Every Rig
Packed with flexible connectivity, the XS-100 works with every performance setup. Up to two external footswitches or an expression pedal are supported, expanding your real-time control options. MIDI I/O opens the door to more advanced applications, from external MIDI control to sending MIDI commands with the pedal and footswitches. There is also a secondary output that mirrors the input signal, providing parallel routing flexibility for sophisticated rigs.
