Get to know them!

Compact and stage-ready, the BOSS XS-1 Poly Shifter lets your guitar do the work of three. With a single press, the XS-1 allows you to change tuning, conjure shimmering textures, or add wild, octave-bending layers to your solos. With its intuitive layout and straightforward design, the XS-1 puts creativity at your fingertips, featuring controls to blend your signal and a range that spans up to 3-octave shifts in either direction. Whether you need to drop tune for one song or want to add an octave to your arpeggios, the XS-1 provides a crisp, clean signal thanks to its proprietary Adaptive Focus method technology and 24-bit converters. Many Sweetwater guitarists stomp on the XS-1 when one guitar isn’t enough, and with its seven semitones and 3-octave range, your sound is sure to soar.

Endless tonal possibilities

A simple layout makes the XS-1 an excellent choice for any player. The Balance knob lets you blend dry and effected signals. At the same time, the Toggle/Momentary switch gives you sustained or temporary shifts, and the rotary Shift knob lets you dial in semitone steps and octave jumps with ease. You can even choose your desired shift direction with the Detune switch, allowing you to send your pitch up or down. Plugging in an expression pedal unlocks even more control, allowing for sweeping, hands-free pitch bends for maximum tonal drama.

High fidelity conversion

Behind the scenes, the XS-1 relies on 24-bit converters with Roland and BOSS’s proprietary Adaptive Focus method (AF). This cutting-edge tech vastly improves the signal-to-noise ratio, delivering a cleaner tone and more detail in every note. The result is high-fidelity pitch shifting that sounds natural whether you’re detuning for a heavier riff or soaring into octave-stacked leads.

BOSS XS-1 Features:

  • Polyphonic pitch-shifting pedal for momentary or sustained tone shifting
  • Balance knob blends dry and effected signals
  • Rotary Shift knob with 7 semitone steps, plus 1, 2, and 3 octave jumps
  • Detune shift direction switch for upward or downward movement
  • Expression pedal input for real-time pitch control
  • 24-bit AF method conversion reduces noise and preserves tone fidelity
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
