Originally posted by eladanelf:Well there is not one pedal for most of the U2 sounds, I would say that a delay, reverb and some distortian pedal can do some basics. I use a multi effects unit, it's a low budget boss gt-8 with an additional behringer rv600 for the shimmer sound. It needs some dialing in but you can get a lot of U2 sounds out of it. Check out Roberto Marra on youtube, he has some very good U2 sounds, he also uses a boss gt-8. There are ofcourse much more expensive units like the axe-fx that can do the job better, but if you are on a budget it works very well.
