Boss GA-FC EX

Great accesory for the Katana

It could be a little pricey, but is very well constructed (as normally Boss hardware is), and it can take even some abuse with no doubt.

The case is metallic, very sturdy, the buttons are quality ones, easy to access (it could require an initial learning curve to get use to the distances between them) and allow us to access the patches or the effects as needed.

It support even the use of expression pedals and also to control a second katana, but I didn't use any of that yet.

Right now I'm enjoying changing effects and patches while playing with minimum effort.

The only thing to take on count, is that the included TRS is fine for home use, but it could not be enough for stage use in my opinion, so in that case you may need to buy an extra cable for that.

Fantastic

This totally transforms the ability of the amp.

Super !

Works as intended, good quality !
