Pro tones for every player

Decades of bass tone expertise, all in one box. The GX-1B gives you 16 expressive AIRD amps and over 130 effects straight from the legendary Boss library. Want to mix things up? You can reorder effects, run eight blocks at once and even use a volume pedal and noise suppressor — perfect for crafting setups for any genre or gig.

Effortless sound building

Whether you’re tweaking presets or starting from scratch, the Boss GX-1B makes tone creation a breeze. Borrowing the smart interface from the GX-100 and GX-10, the hexagonal effect buttons show you exactly what’s going on. Tap to switch effects, hold to dive into the details. And with 99 ready-to-play presets and 99 user slots, you’ll never run out of space for your custom sounds.

Dial in tones fast with Gear Suite

The GX-1B introduces Gear Suite, which is a game-changer for quick sound design. Each amp and effect comes with factory-tuned, pro-grade settings you can recall instantly. Want to tweak? Go for it, then save your faves for instant access whenever inspiration strikes.

Freedom to perform

Once your tones are locked in, take control on stage. Assign footswitches and the expression pedal to anything — from simple on/off to multi-parameter sweeps. Add wired or wireless controllers for even more flexibility. And with three power options (batteries, AC or USB), you can play anywhere!

Your everyday creative sidekick

The GX-1B is built for modern bassists. Hook up via Bluetooth or USB to jam along with tracks or record straight into your DAW. Dive deeper with BOSS Tone Studio — play along with YouTube songs and lessons, loop tricky sections, slow things down and sharpen your skills with built-in rhythms and a metronome. Plus, explore pro sounds on Boss Tone Exchange within the app.
