The Boss GA-FC EX Foot Controller takes your amp control to the next level with rugged build quality and intuitive performance options. Designed around a tough metal chassis with six heavy-duty footswitches and crisp two-color LEDs for real-time feedback, this controller lets you switch channels, toggle effects, and control multiple parameters without ever taking your hands off your instrument. Dual expression pedal jacks and an extra control jack with a three-way mode selector give you expanded control — whether you’re adding a third pedal or customizing your signal flow — all through a simple 1/4-inch TRS connection that needs no external power.

For guitarists running complex rigs or multiple amplifiers, the GA-FC EX shines. Engage EXPAND mode to link more foot controllers for even broader control, or use FOOT CONTROL 2 mode to split control across two amps for synchronized or independent switching. Its compatibility with select Katana Gen 3 and MkII Series amps means players can access preset memories and effects with confidence and ease, elevating both practice and live performance. Available at Haggerty’s Music, this footswitch strikes the perfect balance of pro-grade functionality and stage-ready reliability that serious players will appreciate.
