The BOSS Foot Controller enhances the standard GA-FC with expanded functionality for select BOSS amplifiers, maintaining a simple and intuitive setup. It features a rugged metal chassis, six heavy-duty footswitches, and two-color LED indicators for clear visual feedback. With two expression pedal jacks and an additional control jack with a three-way mode selector, it offers versatile configurations. 'Expand' mode lets you connect another GA-FC EX or GA-FC for more footswitches, while 'Foot Control 2' mode enables control of two Katana Gen 3 or MkII amps simultaneously. 'Exp Pedal 3' mode supports a third expression pedal for added flexibility. It functions as a standard GA-FC with other amp models and connects via a single 1/4-inch TRS cable (included) with no external power required. Designed for seamless stage and studio use, this foot controller provides enhanced control and versatility for guitarists seeking maximum performance flexibility.
