Intro and main Riff:

E|---------------------------------------------|
B|---------------------------------------------|
G|---------------------------------------------|
D|------------------------55-55-55-55----------|
A|-2-33-33-33-33-33-33-33-33-33-33-33----------|
E|-0-11-11-11-11-11-11-11--------------3-4-3-0-|
      .. .. .. .. .. .. ..
This is pretty much the main stanza throughout the song
except there is a second guitar that comes in after the intro
is repeated twice.

Alternatively, you can just hit the A (G# in this tuning)
string to fill that sound in...or play it as a power cord.

The Riff before the chorus is the basic main Riff with the ending
played slowly....
