I played it for a guitarschool show, a long time ago, on bass, the riff is almost

E|---0-0-0----0-0-0-0-3-0-5--| repeat x2

but, the really correct version should be,

E|---0-0-0----0-0-0-0-3-0-5--5-3--0-0-0----0-0-0-0-3-0-5

the 5-3 is played is played fast/bluntly, uhm, ah well, play it and you'll hear it!
