Double your power with BOSS’s 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. BOSS’s 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.
