I think this tab is 100% correct.  STANDARD TUNING


  Intro:

 E-------------------------------------------------------
 B--------------------------------------------P----------
 G-------1----------2------------2--1--------4/0---------
 D-------------------------------------------------------
 A-------------0-----------0-----------2---2-------------
 E --0-------0-----------0-------------------------------


  Heavy Verse: (the part with distortion)

 E-------------------------------------------------------
 B--------------------------------------4----------------
 G----------------2--2--2---------------4--4--4----------
 D---2--2--2------2--2--2-----4--4--4---4--4--4----------
 A---2--2--2------0--0--0-----4--4--4---2--2--2----------
 E---0--0--0--00----------00--2--2--2--------------------

    you have to pick the open notes down then up fastly and keep a steady rythym though the whole thing.

  Last two chords at very end of song:

 E----------------
 B----------------
 G--1--------------
 D--2--2----------
 A--2--2----------
 E--0--0----------
