Boss GX-1B Bass Effects Processor

A complete bass rig in a compact pedal — 16 AIRD amp models, 130+ effects, and studio-grade recording in a unit that fits in your gig bag.

Who Is the GX-1B For?

If you are a bassist looking for a single, portable unit that covers practice, recording, and live performance without compromising on sound quality, the GX-1B is built for you. It is designed specifically for bass from the ground up — not a guitar processor with a few low-end tweaks. Whether you are a newer player exploring effects for the first time or a seasoned working bassist who needs a reliable backup rig (or a lightweight travel solution), the GX-1B gets you to professional-quality tone quickly. The Gear Suite system and 99 dialed-in presets mean you can be playing great sounds within minutes of opening the box, and the Bluetooth streaming and USB-C audio interface make it just as useful in the practice room or home studio as it is on stage.

Sound, Feel, and Use Cases

The AIRD amp models in the GX-1B range from round, warm vintage tones to tight modern high-gain voicings with enough headroom to keep your low end defined. Because the processing is 32-bit floating-point at 48 kHz, the signal stays clean and dynamic even when you stack multiple effects. The expression pedal with toe switch opens up real-time control for wah, volume swells, or parameter sweeps — and the three assignable footswitches give you quick patch switching or momentary effect toggling right under your foot.

On stage, the GX-1B's rugged metal chassis and battery power option mean you can set up anywhere without worrying about finding an outlet or a power adapter. In the studio, the USB-C interface sends your processed signal straight to your recording software at full quality. And during practice, streaming Bluetooth audio through the headphone jack lets you work through songs at your own pace without waking the house.
