BOSS XS-100 Poly Shifter
With the
BOSS XS-100 Poly Shifter, BOSS has taken creative pitch shifting to a whole new level. A true expression workstation, it combines impeccable sound quality, an unprecedented transposition range of
8 octaves, and advanced controls that offer total freedom to guitarists and bassists. Whether for simple drop tuning, capo simulation, realistic doubling, or extreme pitch bending effects, the XS-100 opens up previously unattainable sonic horizons.
A unique tool for expression
Equipped with an ultra-smooth pedal, the XS-100 allows you to
slide linearly over 4 octaves, up or down, with remarkable precision. Its integrated end-of-travel switch instantly triggers customizable pitch jumps, ideal for striking effects in live performances. Add to that two assignable footswitches, and you get expressive control that goes beyond the capabilities of traditional pitch pedals.
Next-generation sound performance
Thanks to the latest BOSS algorithms and a specially designed DSP, the XS-100 reproduces every attack and nuance with natural clarity. Complex chords, long solos, and powerful riffs retain their clarity without artifacts. The Detune function (+/- 50 cents) enriches your playing with thick, musical doubles, while the pedal's response and curve settings allow you to tailor the feel perfectly to each musician.
Customization and built-in memories
The XS-100 doesn't just offer ready-to-use effects: it allows for extensive customization. Each function of the pedal and switches can be reassigned, and pitch, speed, and curve settings can be adjusted with precision. Once you've created your sounds, you can save them to one of the
30 memory slots for instant recall during live performances or in the studio.
Advanced connectivity and integration
A true creative hub, the XS-100 integrates seamlessly into any setup. It features a
dedicated analog output that duplicates the input signal for parallel routing, a USB-C port for system updates, and MIDI TRS jacks (in/out) for communication with advanced setups. Two external footswitches or an additional expression pedal can be connected for even more real-time control.
Who is it for?
This model is designed for
professional guitarists and bassists looking for extreme versatility and uncompromising expressive possibilities. Ideal on stage for changing tunings in an instant, it also has its place in the studio for enriching arrangements or experimenting with new textures. Musicians who already use pedals such as the
BOSS PS-6 Harmonist or the
OC-5 Octaver will find this to be a much more comprehensive and flexible tool.
