Walrus Audio is proud to offer the Xero Polylooper, a true bypass, dual-channel stereo looper that fully explores the creative possibilities of multiple loop channels, providing a rich and unique feature set for how multiple loops can interact. With two fully independent loop channels, playback speed and direction control, and three flexible loop modes, the Xero Polylooper is a performance-ready tool that pushes looping into new dimensions. Built with Walrus Audio’s acclaimed design ethos and powered by the advanced and proprietary MDSP Module, the Xero makes complex looping intuitive, visual, and inspiring.

Key Features

  • Dual-channel stereo looper with full separation.
  • Independent volume, pan, speed, and reverse per loop
  • Three loop modes: Sync, Unsynced, Polyrhythmic.
  • Up to 3 minutes of loop time with unlimited overdubs and near infinite stacking.

Three Loop Modes

The Xero features three different modes to experience all new ways of creating, building, and interacting with loops:

  • SYNCED MODE – Locks both channels to the same length and time base, but allows for independent level, effects, and playback control. This mode is great for classic looper functionality with convenient channel strip style controls for separate looped elements.
  • UNSYNCED MODE – Allows both channels to operate with fully independent time bases, allowing loops to organically drift in and out of sync with one another. Great for creating unpredictably shifting ambient pads, perfect for anyone using pedals for ambient sound design.
  • POLYRHYTHMIC MODE – Allows the user to record loops of different lengths that share a common time base, meaning they will stay rhythmically synced in time. This allows the user to record a 3 beat pattern against a 4 beat pattern (or any other polyrhythmic division), a short phrase against a long phrase, or a long phrase against a short phrase. In this mode, the recorded loop lengths will automatically quantize to a multiple of the shared time division relative to the first recorded “base” loop.

    Looper

    A looper pedal records and plays back sections of your playing, allowing you to layer sounds and build full arrangements on your own. By capturing short or long phrases, you can create rhythm parts, harmonies, or entire backing tracks in real time. Most loopers offer basic controls for record, overdub, and playback, while advanced models include multiple tracks, tempo syncing, and memory storage for saving your loops.

    Loopers are invaluable for practice, songwriting, and live performance. They help you explore ideas, refine timing, and experiment with textures — from solo acoustic performances to complex ambient soundscapes. A good looper pedal becomes an instrument in itself, letting you improvise, arrange, and perform with creativity and freedom, turning one guitar into an entire band.

    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.

    Volume

    Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
