Manufacturer's ID: GT-1
What we say:
Inside a sturdy metal box not much bigger than the average adult's foot, Boss have crammed an Aladdin's cave full of tones, amps sims and effects, all ready to use and all extremely impressive sounding!
The GT-1 crams in so much besides great tones, though: you get a treadle pedal for expression, a Control switch for extra functionality and real-time control, a USB output for direct connecting to a computer and a 32 second phrase looper too. Phew! That is a lot of content!
This is all managed with the minimum of knobs and switches to keep things simple and easy. Instead, players can use a dedicated software editor and BOSS's Tone Central to upload, write, swap and download patches with a large online community. The sounds already onboard are all super-high quality: indeed they should be; this is a fully paid up member of the GT family, BOSS's powerhouse flagship multi-effect processor line.
With it's small footprint and ability to run on either an adapter or batteries, the GT-1 will go with you unnoticed inside your gig bag and give you tones from tasteful to monstrous when you reach the gig.
A streamlined interface enables quick and intuitive sound creation, while an assignable control switch and expression pedal provide dynamic real-time effects adjustment. And by connecting to BOSS Tone Central, you can download free pro patches, editing software, and more. Equally suited for beginners, weekend warriors, and traveling players, the GT-1 packs premium sound in a compact and rugged package.

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.
