This is the BOSS GT-8. It is the most powerful guitar effects floor processor that BOSS makes and is the flagship of their multi-effects pedals. This is by far, the best mult-ieffects processor out there and, like all BOSS effects pedals, it's built like a tank. Here are some of the things it offers:

Dual COSM Amps
The BOSS 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 in the BOSS GT-8 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. The BOSS GT-8 has it all!

Solo Switch
Step into the spotlight with the BOSS GT-8 and the new Solo Switch feature. Each of the 46 COSM amp models in the BOSS GT-8 contains a specially programmed variation that's optimized for soloing. Simply click the Solo switch to activate the lead tone, and off you go - it's like having a separate solo channel on every COSM amp!

Extreme Effects
Forty-four effects categories are built into the BOSS 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 BOSS GT-8, plus 140 user patches for storing your custom amp/effects creations. As a special bonus, there's a selection of synth waves onboard, plus sitar and an acoustic processor. From subtle to sizzling, where will you take your tone?

Effects Chain
Another area where the BOSS 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 you'd care to take your tone "outside the box" and incorporate some external effects into the BOSS GT-8's signal path, you can do so with the Ext Loop send and return. Flexibility in routing is the name of the game.

Connectivity
The BOSS GT-8 is stocked with enough I/O options to satisfy even the most demanding pro. In addition to its stereo analog outs, the BOSS GT-8 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.
