this is only the strumming part of the song and i don't know how accurate it is, but it 
pretty close.this is my first tab so im
sorry if you can't understand my directions...i tried.
~ -let ring
\ -slide down                  :listen to song for strumming pattern
/ -slide up

fig.1 -clean
|-----------------------------------------------|
|-----------------------------------------------|   play this through
|-----------------------------------------------|   twice
|1010101010101010-\77777777\55555555/77777777--/|
|-8-8-8-8-8-8-8-8-\55555555\33333333/55555555--/|
|-8-8-8-8-8-8-8-8-\55555555\33333333/55555555--/|

  then when you slide back up from '335' play
|--------------------|  this instead of strumming for 8.
|--------------------|  then repeat fig.1 four more times
|--------------------|  before the chorus ,
|77------7---7---7---|
|55--------5---5---5-|
|55------------------|

chorus - distorted

|10~---7~---|repeat 4x
