Some studio footage of the band and gear...

[Edge_Orchestra]

Some of those are Adam's bass guitars and Bono is quite the collector too. But there are assuredly loads of guitars that we've not seen on tour.

The Stuck In A Moment Strat was first seen in Rattle and Hum and didn't see use on tour until 2001... And the U2 by U2 book has a pic of Edge with a single-cutaway Gretsch.

I just can't imagine what the Edge's pedal drawer (or wherever he put all of his pedals in). It must be insane.
