So I just recently got one of the older FBV Express models but, the thing is it doesn't seem to be working. I plug it in and it lights up, but pressing any of the footswitches does nothing. When I try to calibrate it I hold A and D until the lights go out and and when I press the toe switch on the wah/volume pedal the wah light never comes on, the volume light does.

I'm using a Spider Valve 212 (the older model)

Any help will be very appreciated. Thanks!
