Hi!
very nice Profiles/Videos! Here´s a Tip to get as close as possible to The Edge´s Sound. In my opinion the essential thing is to use the same Picks he uses.
Look here:

Take the blue ones and hit the strings with the "nopped" Side. It makes a very, very, very huge difference!!!
That´s the secret of his basic Sound.
Also important is to turn up the mod-level in your delay settings.
So if you want a sound like "Where the streets have no name"
- get the right pick
- singel coil Guitar
- a lightly crunched amp (VOX AC30)
- delay with lots of modulation
Greetings!
