BOSS GX-1B Bass Multi-Effects Processor - Blue

For bassists who need serious tone without the weight of a full rig, the BOSS GX-1B delivers a compact, performance-ready solution that travels easily without compromise. This ultra-portable bass processor combines 16 AIRD bass amp models with over 130 effects, giving players the depth, punch and control needed for practice, recording and live performance. Purpose-built bass processing keeps low end tight and articulate, while an intuitive color display and hexagon-shaped effect buttons make tone shaping fast and visual. With built-in expression control, USB and Bluetooth connectivity, BOSS Tone Studio app integration and flexible power options, the GX-1B effects processor puts a complete bass rig within arm’s reach wherever you play.

Bass-Tuned Amplifier and Effects Engine for Depth and Control

The GX-1B is voiced specifically for bass, capturing the weight, dynamics and harmonic detail that anchor a great low-end foundation. Sixteen AIRD (Augmented Impulse Response Dynamics) bass amplifier models respond naturally to playing touch, translating fingerstyle nuance, pick attack and dynamic variation with convincing realism. A curated library of over 130 effects—ranging from compression and drive to modulation and ambience—lets you shape tone without sacrificing clarity. With support for eight simultaneous effect blocks, along with a dedicated volume pedal and noise suppression, the GX-1B enables layered, performance-ready signal chains that remain focused and musically supportive across styles.

Clear, Intuitive Interface for Fast Tone Shaping

Editing tones on the GX-1B is designed to feel immediate and intuitive. Hexagon-shaped effect buttons visually organize sound categories, allowing effects to be engaged or bypassed instantly, while deeper parameters are accessed with a simple long press. The high-resolution color display presents signal flow and edits clearly at a glance, keeping attention on feel rather than menu navigation. With 99 factory presets and 99 user memories, moving between polished starting points and personalized sounds is quick and reliable.

Gear Suite Presets for Efficient Sound Building

Gear Suite streamlines tone creation by pairing each amp and effect category with professionally voiced parameter sets. With minimal adjustment, bassists can recall complete, musical sounds that serve as dependable foundations for practice, recording or performance. These settings can be refined and saved into user Gear Suite slots for instant recall, making it easy to adapt tones to different songs or playing contexts without rebuilding patches from scratch.

Expressive Performance Control and Modern Connectivity

Built for real-world performance, the GX-1B offers hands-free control that adapts to different playing environments. Three freely assignable footswitches and a built-in expression pedal with toe switch allow real-time control of effects, volume and multiple parameters at once. Bluetooth connectivity enables wireless playback from mobile devices for practice and rehearsal, while USB-C supports direct recording and playback with computers and mobile systems. Multiple power options—including AA batteries, AC adapter or USB bus power—ensure uninterrupted creativity wherever you set up.

A Portable Bass Rig Designed for Mobility

Compact, lightweight and ruggedly constructed, the BOSS GX-1B is designed to move easily between home, studio and stage. Its small footprint fits comfortably into a gig bag or backpack, while its professional sound quality supports everything from solo practice to full-band performance. By combining bass-focused amp modeling, flexible effects, intuitive control and seamless device integration, the GX-1B multi-effects processor turns virtually any space into a dependable bass environment—allowing players to focus on groove, feel and musical connection wherever they plug in.
