This is pretty much the main riff to the song, also this is my first tab so dont rat on me if it seems wrong, allthough it sounds pretty good to me. 

Standard tuning [E A D G]

G|------------------------------------------------------------------|

E|-5-5-5-5--0-0-0--2-2-2-2-2-2-2-2---7-7-7-7--0-0-0--2-2-2-2-2-2-2-2|

Enjoy
