New Walrus Audio Xero Polylooper Looper Guitar Effects Pedal Cream

The Xero Polylooper is a true bypass, dual-channel looping powerhouse with independent loop control on each channel, stereo panning, variable playback speed, reverse playback, three looping modes, and intuitive stomp gestures. The Xero is your new partner for perpetually endless ways to create new song ideas, practice your licks, or build endless textures on stage.

Two Loop Channels, Fully Independent Control
Xero gives you two independent loop channels—each with its own:
Loop up to 3 minutes with near infinite stacking of loops
Unlimited overdubs
Volume and Pan controls
Playback speed (0.5x / 1x / 2x)
Reverse playback option
You can loop on each channel individually or stack them together to build complex, layered compositions—all in real time.

Play Naturally. Control Effortlessly.
The Xero's dual stomp switches keep loop control fast and intuitive:
Tap the left stomp switch to record and playback loops
Hold the left stomp to undo
Tap the right stomp switch to stop loop playback
Hold the right stomp for speed FX
Double-press both switches to toggle channel control
Double-hold to trigger full stop or full erase
Need even more control? Plug in an external dual-stomp switch to simultaneously take full command of both channels—perfect for live performers and loop-centric setups.

Looping Modes Built for Any Workflow
Switch between three flexible loop sync modes:
Sync Mode – Keeps all loops time-aligned to the first recorded loop
Unsynced Mode – Let each channel record loops of completely independent lengths
Poly Mode – Create polyrhythms using shared time divisions (3:4, 5:7, etc.) for interlocking textures (Supports MIDI clock for precision syncing)

Visual Feedback That Keeps You Locked In
Each channel has its own multicolor LED system showing recording, playback, speed effects, and channel control status.

Speed FX & Direction Controls
Activate Speed FX to unlock Half / Normal / Double speed and Reverse playback. Each channel's playback behavior can be manipulated independently, letting you remix on the fly. FX activation syncs to loop start in Sync and Poly modes, ensuring accurate timing.

Bypass That Listens
The Xero features true relay bypass—when no loops are active, the pedal automatically disengages, keeping your tone completely untouched.
