BOSS Introduces GX-1B: Ultra-Portable Multi-Effects Powerhouse for Bass
BOSS has announced the GX-1B, a new ultra-portable multi-effects processor designed specifically for bass players who want premium sound quality and deep functionality in a compact format. Drawing on BOSS’s long-standing expertise in bass amplification and effects, the GX-1B combines modern processing power with a streamlined, gig-ready design. At the core of the GX-1B is BOSS’s AIRD (Augmented Impulse Response Dynamics) technology, delivering authentic valve-style amp tone and feel optimized for bass. The unit features 16 bass amplifier types and over 130 BOSS effects, covering everything from foundational clean tones to drive, modulation, ambience, and more experimental textures. Despite its small footprint, the GX-1B allows for serious signal-chain flexibility. Players can run up to eight simultaneous effect blocks, in addition to a dedicated volume pedal and noise suppression, making it possible to build complex, professional-grade patches without compromise. The unit ships with 99 ready-to-play presets, alongside 99 user memory slots for custom sounds. Operation is designed to be fast and intuitive. A full-color display and category-based controls simplify navigation, while the Gear Suite function allows players to quickly configure amp and effect combinations with the press of a button. Three onboard footswitches and an expression pedal with toe switch are fully assignable, offering hands-free control in live situations. Audio quality is a clear priority, with 24-bit AD conversion, 32-bit DA conversion, 32-bit floating-point processing, and a 48 kHz sample rate ensuring clarity and headroom across all playing styles. The GX-1B also supports WAV cabinet IR loading, giving players additional flexibility when shaping their output for stage or studio use. Connectivity is another strong point. Built-in Bluetooth® allows wireless playback from a mobile device for practice or jamming, while USB-C® audio and MIDI support enables direct recording and playback with computers and mobile devices. The GX-1B integrates with BOSS Tone Studio on macOS, Windows, iOS, and Android, providing deep editing tools, practice features, and access to the BOSS Tone Exchange for sharing and downloading Livesets. For expanded control, the GX-1B includes a jack for up to two external footswitches or an additional expression pedal and supports wireless control via the FS-1-WL footswitch and EV-1-WL wireless expression pedal. Power options are equally flexible, with support for three AA batteries, AC adapter, or USB bus power, making the GX-1B suitable for everything from desktop practice to fly dates. Its compact, lightweight design allows it to fit easily into a gig bag or instrument case pocket. With the GX-1B, BOSS continues to refine its bass-specific digital platform, offering a highly portable solution that doesn’t sacrifice tone, control, or professional features. BassGearReviews.com will be following up with hands-on testing and a full review once the GX-1B becomes available.
