OK.  This is an easy song to learn.  You simply have to tune your guitar into drop-d. That would make the tuning look like this...

E------------
B-----------
G-----------
D-----------
A-----------
D-----------
^
Note that the E string tunes DOWN to D.  That's pretty obvious though because if you tried to tune up that far then you would probably break more than just a string.

Anyways....
To get the right distortion you can either go out and buy a Korg AX1000G and set it on Warpigs like I do, or, you can fiddle around with a mixture of distortion and ambiance.  Mine is set on Big Fuzz distortion and an echo effect called Plate.  But, if you can get it to work with something else, GO FOR IT!!

Here it goes.

Intro:
E---------------------------------------------------------------

A-5-0--------2-2-2-2-2-2-2-5-5-10-10-10-10-10-10-10-5-5-5-5-5-5-5-5

Repeat 4 times.  After the first don't hit the 5-0.
