Expanded Floor Control for Select BOSS Amplifiers

The GA-FC EX provides expanded foot control functionality for select BOSS amplifier models. It maintains the simple setup and intuitive workflow of the standard GA-FC while offering additional functions for greater performance flexibility.

Rugged metal chassis and six heavy-duty footswitches
Control channel selection, effect on/off, and more
Two-color LEDs for easy view of control status
Two dedicated expression pedal jacks
Additional control jack with three-way mode selector
EXPAND mode for adding another GA-FC EX or a GA-FC
FOOT CONTROL 2 mode for operating two amps at once
EXP PEDAL 3 mode for a third expression pedal
Works as a standard GA-FC controller with other amplifier models
Connects with a single 1/4-inch TRS cable (included)—no power required

More Power and Flexibility
The GA-FC EX builds on the standard GA-FC with several enhanced features. Status LEDs with two colors 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.

Enhanced Performance Control for Katana MkII Amps
The mode selector on the GA-FC EX opens up powerful control capabilities with supported Katana MkII models.

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 Two 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.Compatible Products

THIS ITEM WORKED WONDERS FOR ME..
DURING THIS WINTER SKIN PROBLEMS WERE PRESENT SO I TRIED THIS ITEM, AT FIRST I NOTICED THAT IT MADE MY SKIN FEEL REALLY DRY BUT IT DID CALM MY SKIN DOWN TO THE POINT WHERE THE ISSUES, WHICH WERE BECOMING INTENSE, JUST DISAPPEARED AFTER I USED IT 2-3 TIMES EVEN ON MY FACE, SO PERHAPS DRYNESS IS WHAT ENDED MY SKIN ISSUES (PSORIASIS) I HAVE EXPERIENCED IN THE PAST USING OILS AND CREAMS WHICH HAVE MADE MY ISSUES WORSE SOOOOOO THIS ITEM WAS A SUCCESS FOR ME.

Fantastic soap for the dermatitis and eczema prone
You guyyyyysss, my hands have no dry, itchy spots right now. None. This is remarkable because before now I have for years had issues with eczema/contact dermatitis patches that have at times (aka: most times) been pretty unbearable. To say that I’m overjoyed to have found a natural soap that truly works for me is an understatement. When you use this, you can feel that it’s moisturizing your skin. It’s fantastic. If you haven’t tried it, do yourself a favor and get yourself a bar. I’m wondering now if I can use it on my entire body and to wash my hair. That’s probably a little overboard, but it’s that good and now that I’ve used it I suspect all my skin problems are contact dermatitis that could be solved by the right soap/shampoo.
