the whole song is played with these three chords:

  E          B7          A
--0----------0-----------0-----------------------|
--0----------0-----------2-----------------------|
--1----------2-----------2-----------------------|
--2----------1-----------2-----------------------|
--2----------2-----------0-----------------------|
--0----------------------------------------------|

in that respective order.  for the verses palm mute and strum
only the lowest three strings.  on the chorus...let it wail.
enjoy.  for any questions or comments email me at
