Boss GT-1 Product Overview by GAK

The Boss GT-1 is a state of the artmulti effects pedal designed to give you unparalleled sound and exceptional portability. The Boss GT1 takes its sounds from the top of the range Boss GT-100, giving you access to tones you'd typically expect to hear on much more expensive multi effects processors.

Boss GT-1 features standard effects like overdrive and delay, along with reverb and chorus, plus Boss's MDP technology and utility effects like guitar simulation. They've also thrown in a looper for good measure.

The GT-1 is built like a tank, making it the ideal travel partner for gigs. It should slip conveniently into your travel bag. It's either battery or mains powered so you can plug in or take advantage of up to 7 hours of battery life on 4AA batteries. This guitar pedal is really easy to use straight out of the box so even if you're a bit of a technophobe, you'll find yourself fully immersed in the GT-1 for hours on end. Having said that, its loaded with state of the art technology for more technical applications.

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.

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.

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.

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.

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.

  • Mr Walter Nelson-Aylott


    It's the greatest thing I have ever bought in the world of guitars.

  • Mark Halstead


    Great little box! I bought this to run alongside my ME80 as a portable option (it fits in small gig bags pockets) and its superb! A little more fiddly than the ME80 as it’s menus rather than knobs than dials but once everything is set it’s great

  • Paul


    This unit is excellent, it combines all the effects you will ever need in one compact well built unit.

  • Alan White


    Got all you need in 1 compact pedal. Great product. Arrived on time will not hesitate to use GAK in the future

  • Roger McVeigh


    For a small budget FX pedal, this unit is excellent. I bought it for times when I didn't want to take out my VG8/ GT10 combination and once I'd got used to the style of editing, I found it to be very good. There are two downsides. the first is that it comes with a really poor set of pre-programmed sounds which are mostly heavy/ grunge and do not show off the units capabilities. The second is that the manual is one of the worst and least comprehensive that I've ever read. It does not say what the selected parameters achieve and so it takes some time of messing about to work them all out. Some of the factory sounds come with the function of switching two FX off at once but I've been unable to duplicate this facility in other sounds. Bear in mind that I edit my VG8 and GT10, which are complicated units and I do not find them difficult; I also used to submit synthesizer patches which were published in Sound on Sound magazine, so I'm not exactly a novice at this. These two issues are likely to put off many buyers which is a shame and is unusually unprofessional for Boss.
