Take command of your sound like never before with the BOSS GA-FC EX Guitar Foot Controller. Designed for guitarists who need maximum flexibility on stage and in the studio, this powerful controller connects directly to compatible BOSS and Roland amplifiers via the GA-FC jack. With a single stomp, you can switch between four channels, activate two independent loops, or engage reverb and boost functions—all while keeping your hands on your instrument. The GA-FC EX doesn’t stop there. It’s expandable with up to two expression pedals and external footswitches, giving you complete real-time control over volume, drive, and more. Katana MkII users can take advantage of Foot Control 2 mode, enabling simultaneous operation of two amps for even more sonic possibilities. Need more control? Daisy-chain a second GA-FC or GA-FC EX for instant access to every effect and memory slot. Built with rugged metal housing and six heavy-duty footswitches, this controller is designed to withstand the demands of touring musicians. Bright two-color LEDs make it easy to see what’s active at a glance, even on dark stages. Whether you’re rehearsing, recording, or playing live, the GA-FC EX gives you the intuitive, hands-free control you need to unlock the full power of your amplifier.

Perfect for live performances and studio sessions where fast transitions matter.
