Anyone here uses 2 wahs and how do you use them? Stevie Ray has 2 wahs on his pedal board on this SNL performance of "Say What!": http://ca.youtube.com/watch?v=8yYWW3Au5ic but I'm not sure if the second wah is on or if it's an old vibe pedal. Btw, who's that blonde who introduced him at the start? Looks familiar.
