Boss GT-Pro Features: BOSS' most powerful rack mount guitar processor Dual COSM amp section with Solo Mode for instant tone boost Three stereo effect loops Huge array of outputs, including digital Built-in USB-audio interface with bundled editor/librarian software Boss GT-Pro Details: Dual COSM Amp Power With its dual COSM amp-modeling engine, the GT-Pro allows you to construct towering tones by combining any two of the 46 amp models — then layer, switch, or pan between them as your play. Amp channels can even be controlled according to how hard you play (picking dynamics). In addition, no matter which amp model you've selected, you can instantly access a companion lead tone with the Solo Switch. It's like having a separate solo channel for every COSM amp model! BOSS's Best Multi-FX Looking for BOSS's best effects? You'll find them here. As the top of GT line, the GT-Pro provides 44 effects categories, with 200 preset- and 200 user-patch locations. Choose from compressors, overdrives, delays, reverbs, choruses, EQs, wahs, and dozens of other BOSS-quality effects — there's even a sitar and acoustic guitar emulator onboard. The GT-Pro also impresses with its ultra-flexible effects routing. Internally, the 15 effects blocks can be configured in any order you desire; externally, a trio of effects loops plus an array of assignable outputs enables the most flexible signal-routing configurations. Used as a rackmount guitar preamp, the GT-Pro crushes the competition with its advanced internal effects and routing flexibility. Pro Connectivity Drive your tone in luxury through the GT-Pro's top-grade circuitry and balanced outputs. Thanks to its improved signal-to-noise ratio, the GT-Pro offers an incredibly pure signal path. Use the built-in ground-lift switch to keep your signal clean, no matter the stage or studio environment. If you wish to add some serious settings for the stage environments, you can split the signals independently to a couple of guitar amps with the stereo Sub Outs. I/O flexibility is the name of the game with the GT-Pro, as it also provides four 1/4-inch analog audio outputs, a pair of balanced XLR outputs, and three pairs of effects send/returns.
