I just got a used Bass Pod XT Live system.  I want to know if there is something that should be attached to the Volume/Wah pedal that assists the switches between Volume or Wah functuons.  Since it is new to me I may just need to really read the online manual.  I just updated the Flash Memory and the last question it asks is to move the Volume Wah pedeal until the RED LED comes on for Wah and mine doesn't. 

So is the somethine that should be attached to the toe end of the pedal that switches the base plate contact?

Thanks,
