Product Description

The GA-FC EX builds on the standard GA-FC with several enhanced features. It maintains the simple setup and intuitive workflow of the standard GA-FC while offering additional functions for greater performance flexibility. Status LEDs with two colours make it easier to see changes when switching. And along with two dedicated expression pedal jacks, there’s an additional control jack with a three-way mode selector. It allows you to connect a third expression pedal or use the GA-FC EX for expanded applications.

Expanded Performance for Katana MkII Amps

  • Double your footswitches - Set the mode switch to EXPAND and connect an additional GA-FC EX or a standard GA-FC for even more floor control. With twice the footswitches, you have instant access to all memories and effects at once.
  • Operate 2 Amps - If you use two Katana MkII amps in your setup, FOOT CONTROL 2 mode is for you. Connect one GA-FC EX via two cables to select memories and effects on both amps, either together or independently.

It does make using the Boss Katan amp easier to use than the panel, when you get into it.
