reverb or delay or both?

i am lookin for info on what kind of effects mad season and pearl jam use in some of there solos its heavy with echoe and slurred a little like a wah
wandering if anyone may know what the effects are if
anyone one knows what im talkin about lol
any clues would be appreciated
thankyou

Well, I don't listen to the stuff you've just mentioned, but if you are going to buy single pedal effects, buy a delay first, cuz almost every amp has reverb...
I'm not sure about the wah thing you said, but it's probably an Envelop Filter effect, or may be auto-wah ...
Anyway if you are a beginner, get a decent multi-effect pedal, and you'll learn more about effects.
