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.
