Check amnesta.net/edgedelay fantastic site.
Just a little note since I read this often here or on other sites: The amnesta.net site is an interesting site to get some ideas for starters, but some (if not, most) of the info on it regarding delay times is just
dead wrong! Don't rely solely on the sites info and delay times (or any, on that matter): Take a good bootleg (you'll find plenty on youtube if you don't have any), just listen to what Edge is playing and fumble around the delay time until you get close. More often than so, Edge checks in live performances if his setting is right just before the song starts and that's the best timing to hear the delay settings, because you have no one but him in the audio track.
Second, the delay times are just as good as your backing track speed (bpm) or your own preference of playing. I can't rely on the typical "Streets is 362-365 ms" stuff for instance because I personally really like to play the Streets riff a tick slower than usual. Now try playing "Streets" with a Rattle&Hum backing track and you've got yourself a little wild party!
I'd be lying if I'd say I don't ask people for delay times, I've searched this forum like 500 times at the beginning. But truth be told you'll read 20 different ones. It's good to get you started in what direction you wanna go, but to get it "right" the way
you play it, you'll need to set it by your preference.
Hope that helps and I'm not trying to be a wisea** or anything.
