Boss GT-1B Bass Effects Processor
SKU: GT-1BThe BOSS GT-1B Bass Effects Processor packs professional-grade bass tone shaping into an ultra-compact, pedalboard-friendly format. Powered by BOSS's acclaimed sound engine, the GT-1B offers 90 effect types and 198 patches with bass-optimized preamps, including updated classic models and two entirely new designs. Advanced Multi-Dimensional Processing (MDP) effects deliver expressive, dynamic sounds that respond naturally to your playing touch. The built-in 32-second phrase looper is ideal for practice and creative layering on the fly.
Designed for effortless operation, the GT-1B features Easy Select and Easy Edit functions that let you dial in great tones quickly without deep menu diving, while the onboard expression pedal and control switches give you real-time command over your sound. A graphic LCD display keeps everything visible at a glance. USB connectivity enables direct recording to your computer and seamless patch management through the free BOSS Tone Studio editor, with additional patches available through BOSS Tone Central.
Weighing just under three pounds and running on four AA batteries for approximately seven hours, the GT-1B is built to go wherever your music takes you. Its smooth, edge-free design slides easily in and out of gig bags, making it an excellent all-in-one solution for bassists who need premium effects without the bulk of a large pedalboard.
