okay this is my first tab so please go easy on me. its only the intro so maybe
it'll give you a start. its how i hear it and i think its pretty close. ROCK ON!!!

as far as i can tell, it's in Standard tuning.
use lots of distortion and use one crazy-ass effect. i dont know what it is so sorry. 


e--------6-6-4-4-6-6-----6-6-9-9-8-8-----6-6-4-4-6-6-----6-6-4~
b----6-6-------------6-6-------------6-6-------------6-6-------
g--------------------------------------------------------------
d--------------------------------------------------------------
a--------------------------------------------------------------
E--------------------------------------------------------------

i'm not sure but i think the e-4~ , might be e-4h5 or e-4/5. not sure, just a suggestion.
thanks and enjoy
