Just thought I'd put in a good word for a couple of products some of you may find useful:
This1smyne E2 dual footswitch (with normally open switches): solidly built, super compact, no battery required, works perfectly with the KPA.
Yamaha FC7 expression pedal: Big and solid, nice rubbery coating, wide throw for more control.
