Boss GT-1 Guitar Effects Processor

Exceptional Sound

Thanks to its Premium BOSS sound engine, the GT-1 provides tone quality and sound-shaping ability that far exceeds typical compact multi-effects. A history of BOSS processing is at your fingers, from classics such as the OD-1 Overdrive to modern effects powered by innovative MDP technology. There’s a huge selection of COSM amp tones on tap too, including vintage legends and BOSS original amps optimized for ideal tone and response. Specialized effects like Acoustic Simulator, Guitar Simulator, and others provide numerous tonal options, and there’s even a looper to enhance your practice sessions and stage performances.

Portable Tone Partner

The GT-1 was designed for musicians on the move. It’s surprisingly lightweight and compact, yet still delivers the rugged durability that BOSS is famous for. The modern design is easy to slip in and out of a guitar bag’s accessory compartment, with no worries of hard edges causing damage to your axe. AC or battery power provides flexibility for any performing situation, and up to seven hours of battery life is available for street performing and other mobile gigs.

Easy Patch Selection and Sound Creation

With the GT-1, it’s simple to find fantastic tones for your style, and just as simple to customize them to taste. Beginners can get great sounds right away, while more experienced players will appreciate how quick and intuitive it is to adjust sounds. The Easy Select function allows you to choose patches by genre, distortion, or effect type, while Easy Edit lets you tweak drive, modulation, and echo tones to perfection with little effort. Dedicated panel buttons provide quick on/off switches for effect groups, and also unlock deep-dive parameters for microscopic fine-tuning.

BOSS Tone Central and BOSS Tone Studio

At BOSS Tone Central, you’ll find tons of free patch collections for playing all types of music with the GT-1. Created by pro guitarists, these patches are dialed-in and ready to use, and make great starting points for advanced players who like to create their own custom sounds. The free BOSS Tone Studio software provides a full-featured editor/librarian for the GT-1, as well as integrated access to all the patch collections at BOSS Tone Central.

Maximum Control in a Small Space

The GT-1’s three footswitches are smartly designed to provide patch selection, tuner access, looper control, and more in a minimal footprint. The dedicated CTL1 switch is freely assignable to functions like tap tempo, effects on/off, and numerous others, while the expression pedal and toe switch are assignable to volume, wah, and various effects parameters. If you crave more control, there’s even a jack for connecting up to two external footswitches or an expression pedal. And in addition to providing access to BOSS Tone Central and BOSS Tone Studio, the GT-1’s USB jack lets you record tones with your favorite DAW.
