A question to all the people who play this, do you use any delay at all when playing the song? In particular the opening riff?

Were you asking as a personal preference, or whether it's called for in the song? I think the guitar magazines often accompany tabs now days with an equipment setting to replicate the sound, so I would look around to see if one of them covered that song.

When I play it, I don't use a delay pedal, just use a fair bit of distortion for the main riff, a wah pedal, and a chorus for some parts.
