Guitar Effects Processor
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Forty-four effects categories are built into the GT-8. Up to 13 effect blocks can be used simultaneously to create complex textures and routings. All of your FX bases are covered compressors, reverbs, choruses, EQs, COSM-modeled wahs, and much more. There are 200 preset patches built into the GT-8, plus 140 user patches for storing your custom amp/effects creations. As a special bonus, theres a selection of synth waves onboard, plus sitar and an acoustic processor. From subtle to sizzling, where will you take your tone? ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Another area where the GT-8 stomps the competition is in its powerful effects routing. Internally, the 13 FX blocks can be configured in any order you desire (for example, you can freely assign an equalizer after a distortion effect or before it). And if youd care to take your tone outside the box and incorporate some external effects into the GT-8s signal path, you can do so with the Ext Loop send and return. Flexibility in routing is the name of the game. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------The GT-8 is stocked with enough I/O options to satisfy even the most demanding pro. In addition to its stereo analog outs, it offers a 24-bit coaxial output for ultra-clean digital transfer, an Amp Control jack for switching between two amp channels on an external amp, an external expression/control pedal input, effects send and returns, MIDI in and out, and a headphone output.
