Description
The NUX NOL-1 A/B Roll Octave and Loop pedal is a compact creative hub that turns any practice space into your own mini studio. Combining a polyphonic sub-octave, intuitive looping, IR cabinet simulation and USB audio, it lets you sketch ideas, build full arrangements and practise silently with inspiring, amp-like tone. Whether you are a guitarist or bassist, it is designed to keep you playing, recording and experimenting without breaking your flow.
Inspired by the spirit of classic studio experimentation, A/B Roll makes overdubbing feel natural and musical. Auto recording means you can start capturing the moment you play, while up to six minutes of loop time with unlimited overdubs gives you plenty of room to layer riffs, harmonies and textures. Add in onboard IR cabinets, headphone output and mobile-friendly USB connectivity, and you have a powerful all-in-one tool for songwriting, home recording and performance.
Octave Power for Guitar and Bass
A/B Roll is just as happy under a bassist’s feet as it is on a guitarist’s board. The dedicated SUB control lets you dial in a polyphonic sub-octave that tracks chords and single notes with ease, adding weight and depth to your loops. From subtle reinforcement to synth-like low end, it is a fast way to make solo performances sound bigger and more complete.
IR Cabinet Simulation and Silent Practice
With seven onboard IR presets covering classic guitar and bass cabinet flavours, A/B Roll delivers convincing amp-style tones straight from the pedal. Place it at the end of your signal chain and plug into the 1/8 inch headphone output for late-night practice without a speaker cabinet. The IR simulation keeps your sound full and realistic, so silent sessions still feel inspiring and musical.
USB Audio, OTG and IR Manager
The USB-C connection turns A/B Roll into a flexible recording and practice interface. You can send high-quality digital audio to your computer or compatible mobile device, ideal for capturing ideas, streaming or sharing loops. Using the IR Manager software, you can fine-tune your sound and load third-party IR files, tailoring the pedal’s response to your own taste and rig.
Effortless Looping with Auto Rec
A/B Roll offers both manual and automatic recording modes, so you can work the way that suits you. In Auto Rec Mode, recording starts the moment you play, removing the need for precise footswitch timing and letting you focus purely on performance. With 24-bit / 48 kHz audio quality, up to six minutes of loop time and unlimited overdubs, it is built to capture every spark of inspiration.
