This the correct way to play the intro

E---------------------------------------------------------
B---------------------------------------------------------
G--3b(4)r3-----------------------xx-3b(4)r3-x-x-x-x------
D----------4---------------------xx---------x-x-x-x------
A--------------------------------xx---------x-x-x-x------
E------------2-0-0-2-0-3-2-0--0-2------------------------

This is the chord played (Clean) before the intro is replayed and zack sings over top of it "Can't waste the day when the night brings a herse"
    After you play that chord a bunch of times play 
    this with distortion on.
e-0
b-0
g-2
d-0----x-2
a------x-2
e-3----x-0
