Okay, thanks! I was a bit leery of jamming the pedal down to make contact, since I was anticipating a footswitch underneath. Just got the beast and I wanted to be gentle.
The unit references a toe switch for the expression pedal. There's a raised piece underneath the pedal that appears as though it would activate a toe switch but it doesn't reach the base of the unit. Is mine missing a switch or am I misunderstanding the setup?
