Groundbreaking Stage Amp with Original Tone

Custom built and supercharged for the stage, the new GA-112 is a unique, powerhouse guitar amplifier. With our latest COSM amp model onboard — Progressive Amp — the GA-112 empowers guitarists with original sound creation, intuitive control, and the ultimate in comfort, expression, and playability. The GA-112, with a single 12" speaker and 100W of power, is perfect for rehearsal studios or small- to medium-scale live venues.

Progressive Amp

Built into the GA-212 and 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 what sound you’re going for, the GA series makes it fast and easy to find with only two volume knobs, three tone-control knobs, 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 your latest changes to panel settings automatically, and you can recall one of four saved settings for all controls with a simple 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 provide easy operation with signature styling. You’ll turn heads with these attractive, road-tough amps, which look as cool as they sound.
