I'm actually thinking about adding another external expression pedal to the FCB1010 in order to program for Kemper variable gain settings. (think Aerosmith's Seasons of Wither)
I'd dedicate the external pedal to volume, FCB pedal #1 = Wah, FCB pedal #2
I really think going this way, I could then consolidate the (same amp) clean, crunch, lead modes I'm accessing separately which would free banks up to store additional bank settings of different rigs.
