I'm actually trying to replicate the sound he gets for "Where the Streets Have No Name" too. I have a crate V-50 tube amp set to clean with a Digitech RP-255 multi-effects unit. I've downloaded some Edge presets from the Digitech site and some others, but none of them produce it quite right. The delay is pretty good, but there isn't quite enough crunch. Particularly the high notes, especially on the intro, sound a bit dead. It needs some more compression or distortion...or something, but I just can't seem to get it quite right. I have an SSL-5 in the bridge position and stock pick-ups in the middle and neck positions (soon to be replaced by SSL-1s). Does anyone have any ideas? Should I re-post this question somewhere else in the forum?
