I'm with you 100% on this
Don't kid yourself. My guitar playing time at home is split between trying to poorly impersonate Devin Townsend playing bad thrash riffs and trying to sound like 90s EVH tone playing bad death metal riffs
Really; an on device demonstration of ANY footswitch configuration would be a welcome thing. Whether it's setting up scene controllers to change a boatload of parameters or using control switches attached to single assignable item in a given block. Seeing how it's done ON DEVICE (while it might be boring visually) would be great. I know even now it's still "just use the editor!" but sometimes; I just don't want to do that.
Of course; I don't own anything FAS right now. Just thinking out loud.
