The Latest BOSS Tech for More Power & More Versatility

With its next-generation COSM processor, intuitive interface, and advanced features, the GT-100 is the top choice in floor-based multi-effects for guitarists everywhere. The Version 2.0 update integrates BOSS’ very latest technologies into the GT-100 for enhanced performance while playing live and recording in the studio.


New COSM Amp Effects & MDP Effects

Version 2.0 adds two new COSM amp models—BGNR UB Metal and ORNG Rock Reverb—to the GT-100’s onboard stable of vintage and advanced amps. The update also brings BOSS’ innovative Multi-Dimensional Processing (MDP) technology to the GT-100 courtesy of Tera Echo, Overtone, and A-DIST effects. In addition, Rotary 2 and Acoustic Guitar Simulator effects types have been added as options in the FX1 and FX2 categories.

Enhanced USB Audio Capabilities

The GT-100’s built-in USB audio interface has been upgraded to four channels for more efficient operation while tracking guitar parts in the studio. You’re now able to capture both processed and unprocessed tones at the same time on separate tracks in your DAW. You can also re-amp dry tracks back through the GT-100 while simultaneously listening to your audio mix through USB, making it easy to tweak parameters to achieve the perfect tones for your songs.


BOSS TONE STUDIO Editor/Librarian and New Patches

With BOSS TONE STUDIO, GT-100 users now have a full-featured software editor/librarian for editing and organizing tones from a Mac or Windows computer. Available as a free download, the software also provides a direct link to the BOSS TONE CENTRAL website, where you can preview and download a growing selection of free GT-100 Version 2.0 patches directly into the effects processor via USB.


Guitar-to-MIDI Conversion from a Normal Guitar

GT-100 Version 2.0 also adds a unique monophonic guitar-to-MIDI function that lets you have fun with soft synths and other MIDI instruments in your computer from your normal axe, with no special pickup required. Powered by newly developed BOSS technology, guitar-to-MIDI conversion works with Roland’s free Guitar Friend Jam software, and also lets you experiment with using your guitar to create MIDI sequences in music production software.
