The XS-100 Poly Shifter redefines pedal-based pitch shifting with groundbreaking BOSS technology years in the making. Delivering natural sound, precision tracking, and deep customisation options, this powerhouse expression machine transforms how you perform with pitch. Glide up or down four full octaves with the ultra-smooth pedal to infuse your music with evocative new colours. Enhance solos by triggering bold shifts with a single footswitch press. Instantly retune your instrument with drop tunings, capo simulations, and more. And with onboard memories, your favourite setups are always ready when you need them.

Key Features

  • Advanced pitch-shifting workstation – The XS-100 utilities class-leading pitch shifting effects for guitar and bass, powered by new Boss algorithms for a clear response and natural feel that retains the fundamental sound character as well as deep control options and an eight-octave range!
  • Effortless in use – Its smooth onboard pedal with integrated toe switch provides linear pitch control across +/- four octaves, providing seamless use straight out the box. With its adjustable pedal curve and response, and fully customisable toe switch, footswitches and momentary pitch changes, configuring the XS-100 couldn’t be easier.
  • Seamless I/O – Integrate this pitch shifter to any rig thanks to its versatile ins and outs, including a dedicated analogue output that mirrors the input signal as well as TRS MIDI, USB and inputs for an additional two footswitches for even more control on the fly.

Natural Sound with Advanced BOSS Technology

In developing the XS series, BOSS engineers pioneered new methods to advance real-time pitch shifting and eliminate the tonal artefacts common in conventional designs. Powered by finely tuned algorithms and a specially selected DSP platform, the XS-100 provides balanced polyphonic performance that feels natural and musical across all playing styles, pickup positions, and pedal setups. Your instrument’s attack and tonal character 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 underfoot, you’re in full command of nearly any pitch effect imaginable. The responsive pedal offers linear control of four octaves up or down, and independent pitch-change speeds for each pedal direction make it easy to produce motor revving tones and other interesting effects. At the end of the pedal’s travel, you can use the integrated toe switch to introduce momentary pitch jumps with adjustable range and rise/fall time. Two footswitches are also available to bypass the pedal shift and quickly retune your instrument at fixed semitone steps across eight octaves.

Customise and Save

The XS-100 gives you the tools to shape pitch effects with precision and personality. Customise the pedal’s 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 alternate functions. Craft rich doubling effects with the detuning option and explore many other ways to refine your sound. Once everything’s dialled in, save your setup to one of 30 memories for instant recall during live sets or studio sessions.

Integrate with Every Rig

Filled with flexible connectivity, the XS-100 flows 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’s also a secondary output that mirrors the input signal, providing parallel routing flexibility for sophisticated rigs.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

Guitar Pedals

Your pedal is like a signature dish for your sound — a flavour-packed creation that transforms the bland ingredients of your guitar into something unforgettable. Each one adds its own seasoning, texture, and heat, turning a simple meal into a feast of tone.

These tasty little boxes sit in a row, like plates on a buffet, letting you mix and match flavours as you play. With one tap of your foot, you can swap sweet for spicy, subtle for smoky, and serve up something completely new. From the comfort food of warm overdrive to the fiery kick of fuzz, from smooth jazz sauce to heavy-metal spice, pedals give players a full menu of options to express their taste.  And just like with food, once you’ve tried one dish, you’ll want to sample them all.

Collecting, trading, and discovering new flavours soon becomes part of the joy of being a tone-loving gourmet geek with a guitar.

MIDI

MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Pitch

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.
