Hey there, cant help having this song in my head at pressent as im sure many others are finding.
This is an awesome meaty riff, played in drop D, the guy who posted the other bass tab 
is very close,
kudos after only playing 3 months, but i think its alot easier to play this way...

D------0h3--2--0-----0-----------------|
A--0h3------------3--------------------|
D-----------------------0--0~----------|


Hope this helps, make the two hammer ons at the start quick to make it sound right,
I havnt had time to go through the song to see if this changes at all or to tab the rest 
so hopefully
other tabs will cover the rest, enjoy!
