Which Fryette Footswitch works with GPDI/IR?

Hi all,
I’m looking for the “Definitive Answer” as to which Fryette Footswitch will work properly with the GPDI/IR? I have a label maker - I can make the button labels say MORE and Norm/Ext.
FC-3B?
FC-3C?
FC-3D?

I’d just as well get one from Fryette, assuming one of them will work?
Thanks!

There is a dedicated one for this. I believe it’s the 3E, but I’m checking on that now to see who has one in stock.

You can also check with sales@fryette.com.
