Built for players who want to layer ideas quickly and capture polished tones without extra gear, the NUX A/B Roll combines a polyphonic octave pedal, looper pedal and IR cabinet simulation in a compact, pedalboard-friendly format. Designed for songwriting, practice, livestreaming and direct recording, it delivers studio-ready sound without requiring an amp or additional interface. Ripe for a slot on your pedalboard, the A/B Roll blends creative loop recording with flexible tone shaping so you can move from inspiration to finished track with minimal setup.
Polyphonic Sub-Octave and IR Cabinet Simulation
A dedicated SUB control adds a polyphonic lower octave that tracks cleanly for both guitar and bass, expanding low-end depth while maintaining articulation. Seven onboard IR cabinet presets provide classic guitar and bass speaker simulations, and the balanced 1/4" output with integrated IR processing ensures consistent direct tone for stage, studio or front-of-house applications. Via USB-C, the IR Manager software enables detailed editing and third-party IR loading, turning the A/B ROLL into a customizable direct-recording solution for modern guitar effects setups.
Loop Recording and USB Audio Workflow
With up to six minutes of loop recording and unlimited overdubs captured at 24-bit/48kHz quality, the A/B ROLL functions as both a performance-ready looper and compact USB audio interface. Normal and Auto Record modes allow manual or automatic recording start, streamlining live looping and spontaneous tracking. USB audio and OTG connectivity support direct connection to phones, tablets and computers for content creation and multitrack capture, while the 1/8" headphone output enables silent practice with full IR cabinet tone. Powered by standard 9V DC and drawing less than 100mA, the compact A/B Roll octave and loop pedal is built for portable creativity without excess complexity.
