Notes:
Lots of extra notes ring out through this riff so play it a bit dirty :)
I also tend to make a near-full E maj shape like this...

so the A-flat rings through sometimes, which I hear in the studio cut.
Lastly, listen to the song for how the main riff changes. (It's only the first half
during the verse, dynamics....)
