Boss Multi-Effects with AIRD Modelling and Gear Suite
The Boss GX-1B is a compact multi-effects processor built specifically for bass players who want premium tone in a portable format. Drawing on AIRD amp modelling and bass-tuned effects, it delivers punchy, responsive sound for practice, recording, and live use. Sixteen expressive bass amp models and over 130 effects can be arranged freely across eight simultaneous blocks, alongside volume and noise suppression.
The colour display and intuitive effect buttons make editing quick and frustration-free, while Gear Suite presets let you dial in professional sounds fast. Bluetooth and USB connectivity allow jamming with tracks, DAW recording, and deep editing via Boss Tone Studio. With battery, USB, or AC power options, the GX-1B is ready to go anywhere.
At Riffs & Licks Music, we think the GX-1B is a smart all-in-one solution for bassists who want serious tone without hauling a full rig.
