This song is played on a fretless bass or with some kind of effect pedal.
He plays it on a 5 string ,not in dropped d tuning.It's a great song.Mad props on Dirk (Alex Katunich) Lance on this work of art.

Theres a rest in the beginning till the bass kicks in.
This is the intro and the chorus.He plays this 2 times for the intro and chorus.Theres one fill he does when he plays the :{e-15\xx-3} part.Every second time in the intro and chorus he plays this instead:
{e-xxx15\-x-6-6}
