Tuning: Drop D (low to high DADG)

There's only one bassline in the entire song, which is played several dozen times 
excepting a short bridge at about 2:40. So, I think it's kind of pointless to include how many 
it's played in each section of the song.

I find it more effective to plug the bass into a regular guitar amp and use heavy distortion.
