My Sweet Fracture (intro) Bass Tab

this is the bass part for the intro to the song. It's possible that I have a few things 
wrong cuz' I don't play bass, I play guitar, but it is 99% correct.

      PLAY 2X         PLAY 2X           PLAY 2X
  
G-----6------7---6 ----6-----7--6- -----6---7---6-----------
D-7-7----7-7---7-- --------------- -4-4--4-4--4-------------
A-----------------  7-7---7-7---7- -------------------------
E----------------- --------------- -------------------------

G------6------7---6-----6---7-9-7-6-------------------------
D-----------------------------------------------------------
A--5-5---5-5----5----5-5--5---------------------------------
E-----------------------------------------------------------

THAT'S WHAT I CAME UP WITH SO IF ANYONE HAS ANY COMMENTS, I'D LIKE TO KNOW IF IT'S RIGHT 
SINCE I DON'T PLAY BASS.
