A modern mini-format that shakes up looper conventions
Following the trend of compact loopers favored for practice and stage use, the NUX A/B ROLL adds an essential feature: a clean and stable polyphonic sub-octaver. It positions itself as an all-in-one solution within the NUX mini range, combining high-definition loop capture and direct projection thanks to onboard impulse responses. The result: a pedal designed for daily practice as well as plug-and-play sets without an amp.Who is it for, and what for?
Guitarists and bassists of all levels will find a versatile tool to work on timing, build textures, and arrange parts. Pop, funk, rock, metal, ambient, or hip-hop: the sub-octaver reinforces riffs, simulated bass lines, and harmonic layers, while the looper facilitates improvisation, sound design, and set preparation. Ideal for personal studios, rehearsals, compact pedalboards, and live use directly into a mixing console or headphones.Technical specifications

Questions frequently asked
What is the looper's recording duration?
The looper offers up to 6 minutes of recording at 24-bit / 48 kHz, with unlimited overdubs.
Does the octave effect work with guitar chords?
The polyphonic sub-octaver follows chords and arpeggios. The SUB knob precisely adjusts the level of the lower octave (-1).
Can the pedal be connected directly to a mixer or headphones?
The main output on a 6.35 mm TRS jack includes an IR simulation and is suitable for direct connection. A 3.5 mm mini-jack headphone output with dedicated volume allows silent practice. Seven guitar/bass impulse responses are integrated.
How does the Auto Rec mode on the Nux AB Roll Looper Octaver IR Loader work?
Auto recording is triggered by playing according to an adjustable sensitivity threshold. The Recording Mode LED shows red in this mode, versus blue for manual recording.
Is it possible to import impulse responses into this pedal?
Through the USB-C port and the IR Manager software, personal impulse responses can be imported. The USB-C also supports audio recording and playback, including OTG with mobile devices.
