This song is pretty easy to get down. Just listen a couple of times through for
timing and you can get it right. 

Main Riff
G:---------------------|
D:-0-0----4~-2~--------|
A:-----4~--------------|
E:---------------------|

That plays through most of the whole song.

Second Riff
G:-----------------------|
D:-0-0------4-4--2-2-2----|
A:-----4-4---------------|
E:-----------------------|

Second riff starts about half way through the song. just listen on when to 
come in.  
Thats it. Thats as easy as the song is just listen for timing and you'll be 
fine. Rate the tab if you want. Peace - Will
