The rugged modern design is easy to slip into 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.

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.
