White Stripes (or anything by Jack White) Black Keys John Mayer John Mark MacMillian Indie Rock bands like: Band of Horses, Real Estate, Deep Sea Diver, Seapony All Spring Reverb Users, heavy in some cases U2 Coldplay Hillsong (which really is the same thing ) Chris Tomlin Fleet Foxes Band of Horses all use some sort of plate, hall, or room reverb, both live and in studio. now if i'm on electric on a Sunday morning, I don't alway use reverb, it depends on the worship leader, the set, and the sound they are going for. but if they want a Hillsong (coldplay, u2) sound then its a mod plate with my nova delay, if it's a younger worship leader with more indie rock sensibilities, it's a tape delay (lightly mixed, no dotted 8th) and a spring reverb or plate. if it's country it's a tight spring with a tape delay slap back. if it's a straight rock sound then no reverb or delay, just a dry over drive. I'm not saying that you're wrong if you don't use reverb, but i'm saying that modern music, thanks to influential producers like Eno, Lanois, and Tbone burnett is reverb heavy.
