BOSS GT-Pro Ultimate Patches

Access 275+ patches built for the BOSS GT-Pro’s dual COSM amp-modeling engine — amp tones, effects, and signature artist sounds pre-programmed and ready to load. This is the full general-purpose library for the GT-Pro, covering a huge range of playing styles from blues to metal.

Load it up and start dialing in professional tones immediately, without manually combining amp models or effects chains from scratch.

BOSS GT-Pro Guitar Effects Processor

The GT-Pro pairs a dual COSM amp-modeling engine with 46 amp models, letting you combine any two to build layered tones and switch or pan between them while playing. The Solo Switch gives every amp model a companion lead tone for an instant solo channel. Top-grade circuitry and balanced outputs keep the signal path clean, with a built-in ground-lift switch and stereo Sub Outs for splitting signals to separate amps on stage. I/O includes four 1/4-inch analog outputs, balanced XLR outputs, three pairs of effects send/returns, and a 24-bit coaxial output for high-resolution recording. With 44 effects categories, 200 preset and 200 user-patch locations, 15 configurable effects blocks, and USB-based patch management via the included editor/librarian software, the GT-Pro is built for players who demand pro-quality results on stage or in the studio.

Frequently Asked Questions

Will these patches work with my BOSS GT-Pro?

Yes. This library is built specifically for the BOSS GT-Pro Guitar Effects Processor and delivered in .SYX format, so it loads directly with no conversion needed.

How is this different from the GT-Pro Artist Patches pack?

This is the full 275+ patch general library covering amp, effects, and artist tones. The GT-Pro Artist Patches pack is a smaller, 50-patch collection focused specifically on signature artist tones and delivered in three formats (.SYX, .GTE, .GTL) rather than one.

Can I use these patches in commercial recordings and live performances?

Yes. Once purchased, the patches are yours to use in unlimited personal, commercial, and live performance projects. Reselling or redistributing the files themselves is not permitted.
