NUXA/B Roll Octave and Loop Pedal - Yellow
1/6
Independent shopping perspective
The Korena take
NUX’s A/B Roll combines a polyphonic lower-octave effect, loop recording, and cabinet simulation in a compact pedal. The SUB control adds a lower octave for guitar or bass, while seven onboard IR presets shape its balanced direct output. Record loops for up to six minutes, add unlimited overdubs, and choose a manual or automatic recording start. USB-C also opens an audio-interface workflow and IR editing, with a headphone output available for silent practice.
Strong match
Who this is for
- Capturing layered practice ideas through headphones with cabinet simulation active.
- Building direct guitar or bass parts for recording without an additional interface.
- Starting loops automatically when spontaneous ideas need quick capture.
