GA-FC EX Enhanced Floor Control for Roland and BOSS amps

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. The GA-FC EX builds on the standard GA-FC with several enhanced features.

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.

Awesome music shop! Very clean, not crowded. Lots of guitars for everyone's musical taste. The staff is super nice, and very informative. I can't say enough good things about Picker's Alley! Thank you so much for serving Southwestern Ontario with such awesome service!!

Great music store. Messaged them about a sale item and they put the last one aside for me until I could get there to purchase.

Tim Clements

Tony is by far the best customer service rep around, He knows his stuff, and is always willing to go above and beyond, I only go to pickers alley, for all my musical needs!!

Ryan Mathews

Excellent service, in one word they know what they are doing just tell them your requirement and budget. Don't worry about price if you see it online it's the same price here in offline too. Best thing is the owner's humour and focus on your requirement more than the sales of the store.

Very very happy and satisfied and will be back for additional requirements.

What a great selection of guitars and amps. Staff is very knowledgeable and friendly. If they don't have what you need chances are they can source it for you. Prices are as competitive as big box music stores so there is no need to look elsewhere. I will continue to support local when I can.
