The Boss GA-FC is an almost essential companion product for my Katana 100 III amp. It is a robust and well made product. The only downside is that Boss’s documentation is quite opaque and I needed help from the Boss support team to understand how to use the Boss Tone Studio to program the switch functions. This was readily-forthcoming (thanks Braedon), but should not have been required.

Pretty good but lead is a bit short for playing on stage
Boss gear is always sound and I trust their quality.
The Boss GAFC GA Foot Controller really adds a lot of extra control when using my Boss Katana Amp in a live situation or just jamming at home. I got the best price when I ordered it from Manny's and it arrived super fast. Perfect !
Really great. Thank you.
No frills and well built..
Needs work to learn how to use it. Works well but haven't tried 3rd party expression pedals Volume, wah
Does what I expected.
Score would be higher but for the very limited instructions which came with the foot control
Excellent quality and value.
Absolutely brilliant. So easy to use. Really pleased with it. The service I received at Manny’s was brilliant.
Great little equipment to go with the boss katana i wouldnt get the amp with out it
This should come with the amp. The correct sticker should also come with the footswitch. Supposedly they came with the amp, but they were nowhere to be seen. Now I have to chase the stickers. Operation wise it's awesome, just not quite perfect in the execution.
Perfect extension of my Boss Katana 100 MKII panel 🎸
Great. Easy to use, tough build.
Exactly what I ordered.
Well built must have accessory if you own a Boss Katana amp!
This foot controller is very solidly built and it is very easy to use. I use it to switch from effects to normal speech so I don't have to ajust the settings every time and you can turn the harmony on and off as need be. You can also mute the whole system between srets. The foot controller also gives you functions that are not available with just the amp.
Definitely worth pairing with your Boss Katana to get the most out of the amp!
