Boss GX-1B Bass Effects Processor

The BOSS GX-1B delivers professional-grade amplifier modeling and effects in an ultra-portable platform that fits in a guitar case pocket. Built on BOSS's legendary AIRD (Augmented Impulse Response Dynamics) technology with 16 bass-tuned amps and over 130 effects, this processor provides the authentic tube tone, touch response, and creative flexibility Wisconsin bassists need—from bedroom practice through professional touring. Intuitive hexagon effect buttons, high-res color display, and innovative Gear Suite feature make sound creation fast and frustration-free. Whether you're a beginning player exploring tones, a worship bassist running direct to FOH, or a touring pro seeking an all-in-one travel solution, the GX-1B delivers no-compromise sound.

24-bit AD and 32-bit DA conversion, 32-bit floating-point processing, and 48 kHz sampling rate ensure studio-grade audio fidelity. Eight simultaneous effect blocks plus volume pedal and noise suppression provide the depth serious players demand. Support for WAV speaker impulse responses allows ultimate tonal customization.

BOSS's new Gear Suite feature contains multiple factory settings for each amp/effect type—recalling complete sets of professionally tuned parameters with a single knob turn. Edit to taste and save favorites in user Gear Suite locations for instant access to personalized settings. No menu diving. No frustration.

Bluetooth connectivity lets you play along with songs from mobile devices. USB-C interfaces with computers and mobile devices for recording in DAWs and music production software. BOSS Tone Studio app (macOS/Windows/iOS/Android) provides Session feature for playing along with YouTube (with AB repeat and speed adjustment), metronome, rhythms, and access to BOSS Tone Exchange for downloading professional sounds.

Three onboard footswitches, expression pedal with toe switch—all freely assignable. Jack for adding up to two external footswitches or expression pedal. Wireless expansion available with FS-1-WL Wireless Footswitch and EV-1-WL Wireless Expression Pedal (sold separately).

Four AA batteries, AC adaptor (sold separately), or USB bus power (computer or mobile battery). Practice, perform, and record anywhere without wall power dependency.
