Progressive Amp

Built into the GA-112 is a new and unique COSM amp model called Progressive Amp. With the simple twist of the DRIVE knob and push of the Boost button, you can morph through a diverse sonic landscape of new amp sounds, from clean to Super Extreme.

Instant Access

No matter which sound you're going for, the GA series makes it fast and easy to find with only two volume knobs, three tone-control knobs, and presence and reverb effects to navigate. From your mind to your fingers, the GA series inspires fast workflow and fluid performance.

Smart Channel

The new Smart Channel feature always saves the latest panel settings automatically, and you can recall four types of settings with a button push. No mystery, no confusion — the glowing LED knobs clearly indicate the positions of each parameter for the four memories, and help you visually check the current settings onstage.

Signature Style

GA-series amps are the brainchild of Roland and BOSS R&D, a world-leading force in cutting-edge sound. These amps feature the latest advancements in tone tech, yet they provide simplistic operation with signature styling. Turn heads with these attractive, road-tough amps that look as cool as they sound.
