Intro bit is heavily palm-muted I think
if you know the song you'll get the timing

Intro:
there's a tiny gap between
the first three notes and the
fourth, but its too small to
add on here Same here

then less muted but still a bit and probably with some effect,
gaps more obvious for a bit
listen to the track to get the timing, but that's right.

The when he breaks it down its bass or some electronic noises, but if you want to play
its something like
(normal pace)

               |                                |
           here it goes back to the normal riff
               but this works better
