Here's what Boss say about the GT-1B:

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.

Mobile Powerhouse

The GT-1B is designed for bassists on the move. It’s surprisingly lightweight and compact, making it ideal for tight stage setups and situations where you need to travel light. The rugged modern design is easy to slip in the accessory compartment of a bass bag, with no worries of hard edges causing damage to your instrument.

AC or battery power provides flexibility for any performing situation, so you can always take your tone with you everywhere you play. Please note that the power supply for this unit is sold separately.

Sound Creation Made Easy

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.
