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.
