ST-Series Engine Power

The GT-1 comes with the leading sound engine from the GT series of multi-pedal units. This delivers a huge range of notable guitar amps and effects that are perfect for a massive range of musical styles.

Boss has built into the GT-1 their FX knowledge and effects processing history! From the OD-1 Overdrive Boss guitar pedal right through to their latest effects powered by MDP technology, as well as their famous COSM amp tones.

Creative Control right at Your Feet

The Boss GT-1 features three footswitches which are designed for you to access patch selection, tuner, looper control and more!

The CTL1 switch can be assigned to functions such as tap tempo and effects on/off, while the expression pedal controls wah, volume and other effect controlling.

All the controls on the Boss GT-1 are designed and positioned for easy access, great for the beginner or pro-musician alike, making this effects unit comfortable and quick to operate!

Sleek and Compact Boss Design

The Boss GT-1 comes in a sleek and compact housing design. Lightweight and portable, the Boss experts have really thought about the musicians and producers when they developed and engineered this unit.

With an offering of dedicated controls and a built-in expression pedal, you can tweak and change the effects sound, simply and easily. Once you get the hang of the unit, all of this will become second nature, letting you quickly change the sound with a turn of the know, or push of the button.

So that you've got full freedom with the GT-1 Guitar Fx unit, you can either power it by an AC Adaptor or 4x AA batteries - giving you up to 7 hours battery life while in constant use. This feature is great for the regular busker or the backstage strummer!

Furthermore, you can add more expression pedals with the GT-1's jack inputs and connect it up to a PC or MAC for recording with its USB port.

Straight out of the box, the GT-1 can be quickly used straight away, which is ideal if you're new to the world of Boss effects. For the more experienced player, you'll be amazed how quickly and simply the inbuilt effects can be manipulated, changed and tweaked.

What's more, the easy select function allows you to bring up patches by genre, distortion, or effect type, and the easy edit feature gives you full creative control overdrive, modulation, and echo tones. Making the Boss GT-1 the best unit to get your desired sound and tone at an affordable price!
