The BOSS GA-FC EX Foot Controller provides musicians an easy yet powerful way to manipulate their tone in real time. BOSS designed this rugged footswitch to unlock the full potential of select Katana and Roland amplifiers, giving guitarists and bassists alike an intuitive interface to instantly switch between stored presets or activate different effects. The GA-FC EX builds on the standard GA-FC model with enhanced features for greater flexibility, including status LEDs in two colors, two dedicated expression pedal jacks and a control jack for connecting a third expression pedal. Whether practicing, recording or performing on stage, the GA-FC EX puts a world of sonic possibilities at your feet.

Instantly Switch Between Tonal Presets

With the GA-FC EX connected to your Katana or Roland amp, you can swiftly toggle between all your saved presets to find the perfect tone for any part of a song. The durable footswitches are designed to withstand years of stomping, ensuring reliable switching when you need it most.

Activate Different Effects On the Fly

A quick tap of the GA-FC EX's Effect switch activates or bypasses a variety of effects for the current channel, allowing you to easily customize each preset. Sculpt your tone by adding effects like reverb, delay, modulation or distortion, then save the edited preset to recall later.

Control Your Sound with Expression Pedals

The GA-FC EX features two dedicated expression pedal jacks, giving you hands-free control over effects parameters for a seamless performance experience. Adjust settings like volume, wah or pitch in real time by connecting up to two expression pedals (sold separately). For the ultimate in flexibility, the Exp Pedal 3 mode even allows you to connect a third expression pedal.

Advanced Connectivity for Complex Setups

Running multiple Katana or Roland amps? The GA-FC EX's Foot Control 2 mode offers an easy way to control two amps simultaneously. For an even bigger setup, the Expand mode lets you connect another GA-FC EX/GA-FC foot controller. With advanced connectivity and control options, the GA-FC EX handles the most complex rigs with ease.

    Works great, you just have to play with it to get the sound you may be looking for. Hooked up to the recommended amp which makes the sound very vibrant and professional. Plenty of features to try especially when using two amps. I would definitely recommend this for a professional or a beginner.

    Works fine. Well made. Maybe a bit overpriced for what it is.

    This is a good replacement to a whole bunch of pedals since I am able to use this with the effects in my Katana. I did have to check out a few how to videos to get it working as it should since I am too lazy to check out the manual. Switching is a breeze without a sudden pop. Definitely worth looking into.

    Does the GA-FC EX controller allow you to turn on/off the Mic Channel's reverb? If 'yes', where would I find the instructions for setting that up?

    This is not a processor, it's a controller. It controls other fx, it doesn't have any of its's own. It can control a wah with the proper expression pedal connected.
