Thanks to the Premium BOSS sound engine, the GT-1 provides tone quality and sound shaping capability that far exceeds typical compact multi-effects. A history of BOSS processing is at your fingertips, from classics like the OD-1 Overdrive to modern effects powered by innovative MDP technology. There is also a huge selection of COSM amp sounds, including vintage legends and original BOSS amps optimized for ideal sound and response. Specialized effects, such as Acoustic Simulator, Guitar Simulator, and more, offer numerous sound options, while there is even a looper to enhance your practice sessions and stage performances.

With the GT-1, it's simple to find fantastic sounds for your style and equally simple to customize them to your taste. Beginners can get great sounds right away, while more experienced players will appreciate how quick and intuitive sound customization is. The Easy Select function allows you to choose patches by genre, distortion, or effect type, while Easy Edit lets you fine-tune drive, modulation, and echo sounds to perfection with little effort. The dedicated panel buttons provide quick on/off switches for effect groups and also unlock deep parameter adjustments for microscopic tweaking.
