To see U2 and the Edge live was a rare joy: a classic quartet with a wall of sound—tight, loud, on key, and possessing a palpable synergy. Edge kept it simple on a Tele for “Vertigo,” but he changed guitars tastefully and often during U2’s Bonnaroo performance, playing at least three different Strats, a Les Paul Custom, a 1976 Gibson Explorer, and a 1966 cherry Gibson SG.

Favorite Edge tone of the night: his overdriven crunch through an SG during “Elevation” in the below video, starting at 5:35.
