What effects do bands such as Bloc Party, The Rascals, some latest Arctic Monkeys stuff etc use?

I'm guessing they use delay/echo of some sort?

thank you

is there much difference between echo and delay though?
they sound pretty much the same..
I seen Mile's kanes pedal board and it had at least 15 so, copying the tone couldn't be that easy
