I would love to get my hands on that tab too. I would also love to see an acoustic version of their song "Left Behind". That's a great song as well. Hell, the whole album is amazing.

Ok, the main 2 chords are most likely

1 0
4 0
4 0
3 2
1 3
1 2

All the other stuff I haven't figured out yet, then again I've been messing with it for about 5 min.

You must be deaf
Those "chords" of yours are earache, and fingeraches too
Real chords are some variations of Fism,D and clean open E for whole song
