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.
BOSSs Flagship Multi-Effects Floor Processor
Double your power with BOSSs new GT-8 floor-based mega processor. Loaded with twin COSM modeling engines, it brings unprecedented performance and tonal control to the stage and studio. The Dual COSM amp section provides two discrete amp channels; you can layer and manipulate each engine independently to create wildly expressive sounds. Thanks to the Solo Switch function, lead sounds can be immediately activated perfect for ripping through the mix. BOSSs mega-popular GT-6 was a smash hit with guitarists, now the GT-8 is destined to become the go-to box for gigging and recording guitarists alike.
-----------------------------------------------------------------------------------------------------------------------------------The GT-8 boasts the latest top-quality COSM amp models with complete dual channel configuration. Explore new sonic dimensions by combining two amp models, or by switching between them during performance. Select a high-gain amp such as Metal Stack and set it for deadly distortion. Then add clarity to the raw power by using the Smooth Drive model on the other channel. Prepare to be impressed as you tap into the expressive Dynamic mode, where two channels can be controlled based on picking strength. Transition smoothly from clean to mean by simply picking harder or softer.
