I do not own a bass and am very new to it. As a result,I have only worked out the main 
riff so far. I will update this tab if I can figure out the bridge.

Main riff:

G| ----------------------------------------------------------------|
D| ----------------------------------------------------------------|
A| ------5-4------5---7-8-9----------------------------------------|
E| -0-2------0-2---------------------------------------------------|

Each time you play the main riff, it should be followed with a slide on the a or e 
string. These slides appear to vary a lot throughout the song, so its best to improvise them. 
Slides to and from the 12th fret sort of area seem to work well.
