BOSS GA-FC EX Foot Controller

The BOSS GA-FC EX is an expanded foot controller designed for compatible BOSS and Roland amplifiers, providing hands-free control over channels, effects, and performance functions during live playing. It is built to extend the functionality of supported amplifier systems, allowing guitarists to switch sounds and control multiple parameters without interrupting performance.

Designed as an enhanced version of the GA-FC controller, the GA-FC EX features a rugged metal chassis and six durable footswitches for reliable stage use. It enables fast switching between amp channels, effect combinations, and preset functions depending on the connected amplifier model.

The controller includes dual-color LED indicators that provide clear visual feedback of active functions and switching states, improving usability in dark stage environments. This helps performers quickly identify whether they are controlling channels, effects, or other assigned parameters.

The GA-FC EX includes two dedicated expression pedal inputs, allowing real-time control of volume, wah, or assignable parameters on compatible amplifiers. It also includes an additional control jack with a three-position mode selector for expanded configuration options, including support for additional expression pedals or extended control setups.

When used with compatible BOSS Katana MkII amplifiers, the GA-FC EX supports expanded functionality such as dual-amp control, expanded footswitch banks, and flexible routing of performance controls. It connects via a single TRS cable and does not require external power.
