Equipped with a bass-tuned version of BOSS’s most advanced sound engine, the GT-1B is absolutely packed with top-quality sound tools. A wide range of preamps are available for shaping your core tone, including updated favorites from the GT-10B and two all-new models. Premium MDP effects like limiter and distortion feature advanced BOSS tech to maintain your instrument’s character and response, enabling free-flowing musical expression. Graphic EQ, T-Wah, and other essentials are on hand too, plus impact effects such as Harmonist, Bass Synth, Defretter, and more. There’s also a complete array of mod, delay, and reverb effects, and even a looper for jamming and on-the-fly creativity.
With the GT-1B’s intuitive interface, it’s simple to build sounds and fine-tune parameters, even if you’re new to multi-effects. Dedicated buttons provide instant editing access to each effect category, which you can adjust straight away via three panel knobs. The buttons also function as on/off switches, and feature status indicators that let you see which categories are enabled at a glance. Easy Select and Easy Edit functions streamline patch creation even more, allowing beginners and pros alike to achieve polished multi-effects sounds with just a few tweaks.
