Boss GX-1B Bass Effects Processor

The Ultimate Bass Companion!

The GX-1B delivers professional sound and features in an ultra-portable chassis for practicing, recording, and performing. With its high-quality bass amplifiers and effects, the processor supplies endless creative fuel. At the same time, the high-resolution color display, intuitive effect buttons, and Gear Suite tools make shaping your sound effortless. The GX-1B is not only rugged, powerful, and remarkably compact, it’s also packed with inspiring tones for every kind of bassist—from beginners to touring pros seeking an uncompromising all-in-one solution on the road.

Professional Sounds for Everyone

The GX-1B packs decades of bass-sound expertise into a versatile processor. Experience 16 expressive AIRD amp models, complemented by over 130 effects from the massive Boss library. Thanks to the combination of a freely configurable effect order, eight simultaneous effect blocks, a volume pedal, and a noise suppressor, you can quickly and easily create custom setups for different styles and songs.

Seamless Operation

Whether you tweak presets or build your own tones, the GX-1B is fast and straightforward to operate. The hexagonal effect buttons—inspired by the GX-100 and GX-10 interfaces—indicate effect categories. You can toggle effects with a short press or access detailed parameters with a long press. Also, 99 ready-to-play factory presets are available, plus 99 user slots for storing your own creations.

Fast Sound-Shaping with the Gear Suite

The Gear Suite in the GX-1B is a powerful new feature for quickly dialing in amp and effect tones. Each amp/effect type offers multiple factory Gear Suite settings so you can call up a full set of professionally tuned parameters with a single knob turn. In addition, you can edit individual effect parameters, save them as favorites to user slots, and recall them later.

Freedom for Your Performance

Once your sounds are set, you can control them live and in real time. Assign any function to the footswitches and the expression pedal—from simple effect on/off to tweaking one or multiple parameters at once. Wired and wireless external control options open up even more possibilities. The GX-1B also offers three power options (batteries, adapter, USB), so you can practice and play anywhere.

Your Daily Creative Partner

The GX-1B accompanies you on all your creative journeys. Connect it via Bluetooth or USB to a mobile device or computer to jam along with songs or record tracks in a DAW. And Boss Tone Studio adds even more: use the session feature to play along with songs and lessons from YouTube, including A/B repeats and speed adjustment. Improve your skills with a metronome and built-in rhythms. You can also access Boss Tone Exchange via the app to get inspired by professional sounds. Various editing tools are available to tweak effects or organize sounds for later recall.
