Exceptional Sound  
Thanks to its flagship-class GT 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 and re-amp tones with your favorite DAW.

Super Value Effects


This is a great smaller kitchen sink style multi effects unit. Featuring a full selection of overdrives as well as delays and reverbs it even includes a looper. Small enough to fit in a gig bag,this is a good selection for the traveling musician who doesn't want to haul around a pedal board. The amp modeling feature sounds good when plugging directly into a board or interface.

Sounds massive


This is by far the best portable multi-effects unit I've seen! Super easy to use and change the presets on the fly. If you wanna dig in there's plenty of parameters to edit so tweak to your heart's content! Works on batteries too so you can take it anywhere, plug a set of headphones and you're ready to go!



FX on a Budget


This processor has tons of sounds, and I mean tons. What surprised me is that they put it in a stompbox, and didn't charge you separately for the foot controller. It can fit in your guitar case, and you can either run it into an amp, or directly to the board at your gigs. Plug in some headphones, and play quietly. If your sound calls for FX, and you're on a tight budget, this guy's more cost effective than buying tons of pedals and cables, and much less expensive than most other decent multi FX.

Great New Multieffect!


Guitar multi effects have long been the way for a player to get a lot of sounds without breaking the bank. Boss has a long history of making great multi effects, and this is the newest one, with the most features and settings. You can adjust presets or make your own. It even includes a tuner!



Legendary effects, affordable price


This new compact multi effect is solid. It houses a bunch of Boss' popular effects in a gig bag friendly board that is easy to use and built tough. Being able to download different presets is a nice added bonus and can be fun for an effect newbie. This is a great option for recording or performance as its size makes it easy for transport.
