about the way he plays it on 360: pretty sure Edge uses some autowah during some parts of the song (or dallas pushes the buttons) because Edge was right in front of us at the Frankfurt gig and I heard the wah.
Yeh Dallas has the same effects board as the Edge is when Edge is on walkabouts he doesn't have to worry about the effects changing I think in Horsens 2 his wag wasn't on though, not too sure
