Product Description


Boss GT-1 Guitar Effects Processor

The GT-1 is an incredibly powerful multi-fx unit in a box small enough to fit in your gig bag! And even though it's small, it's jam-packed with loads of cool features and functions making it an effects unit for you whether you're a seasoned pro or just learning how to play.

It has the famous Boss GT engine for its amp modelling and effects so you can get loads of different tones and sounds out of it and they're all the highest boss quality even including some original Boss sounds like their OD-1 overdrive pedal. It's got a built-in tuner, looper and expression pedal (for you to control wah and other sounds where you want to adjust the sound by using the pedal) and it can be run off of a 9v power supply or with 4 AA batteries.

Choose your patches

It does come loaded with cool presets that will get you up and running, but you can connect the GT1 to your computer and download presets made by people around the world from the Boss Tone Central app to find some weird and wonderful sounds.

There are loads of effects to choose from when you want to create your own patches, and they're really easy to save. You just activate whichever effect you want (you can have more than one on at a time) and adjust the parameters with the 1,2,3 knobs.

Here are the effects you can use:

  • FX1 or Compression
  • Overdrive/Distortion
  • Preamp
  • FX2 or Modulation
  • Delay
  • Reverb

So once you have a few of your favourite patches, you can then run up and down through banks of your presets and sounds.


The GT1 has made recording a breeze. You just connect the GT1 to your computer via the USB output and load up your DAW (Digital Audio Workstation like Garageband or Logic etc.) and you can record and even re-amp if you wanted to.
