Yeah I guess I should of included that. The video I've seen of them playing he was fingering the chords as though they where is regular tuning. Although I'm sure he uses drop D on a few songs. Either way, he plays power-chords from what I hear. If your just picking up the guitar it's good to learn from a song book rather than off the internet. Tabs on the net are sometimes wrong, and you don't want to learn a song wrong thinking it's right. Once you've been playing awhile then start figuring songs out on your own, use the tabs then to check yourself or compare.
