a) SBS has been moved up a notch to Am from Abm of recent years
b) Mysterious Ways sounds like it's just being played on an acoustic but still possibly through the same setup? i.e. the only change is the guitar itself and a small change in how Edge plays the middle 8
c) Ultra Violet has been moved up to E from its traditional Eb of the good old ZooTV days, not to mention the way Edge plays the intro. - still sounds like he's playing through the Explorer.
d) MoS is in Abm, as opposed to Am on the album.
Anyone else made any observations (assuming you're not denying yourselves the luxury of any previews?) re. the rehearsals? Obviously it's difficult to make anything substantial based on sound alone but it isn't impossible
