Boss Product Overview

The BOSS GT-100 Guitar Multi Effects Processor is the next-generation in amp modelling, capable of recreating vintage amps and new Composite Object Sound Modelling (COSM) tones.

The GT-100 recreates every detail of a whole range vintage amps, even their little quirks. The GT-100 doesn't just faithfully recreate these sounds, it also gives you the chance to modify them with the 'Amp Customise' function.

The GT-100's dual-LCD display and eight-knob user interface make it easy to navigate and control. Patches, amps and overdrive/distortions can be created from scratch or modified with the easy-to-use graphical TONE GRID.

The GT-100's ACCEL expression pedal lets you control multiple parameters simultaneously, as well as controlling time-variant effects such as FEEDBACKER, S-BEND, TWIST, etc. The GT-100 also features a handy A/B Channel Divide so you can assign different amps and effects to each channel, allowing you to divide the signal by dynamics and frequency. Each channel can then drive its own effects and amp settings.

    After spending hours reviewing all the “top” multi effects units to use live on stage, Boss won! Excellent high quality effects, amp sims, connectivity ability and build quality. Boss have lead the way for many years in guitar effects, and this unit proves that !

  • Gareth Martin


    There’s a reason this is BOSS’ flagship multi-effects. I have only scratched the surface and I have found every tone I could ever want with a multitude of editable functions. Sheer class.

  • Viktor Balko


    Great Product, haven't had the time to use it to its full potential yet, but the few presets I've tried sound amazing!
