Oh man, one of my favorite albums for sure. Sorry, I don't know if there are any good tabs for it, but I've caught myself humming the basslines enough to try to figure it out by ear.
I don't have a tab off hand...but it's basically a "box pattern" in B. If you play the B on the seventh fret on the E string, All the notes are either at an open, 5th fret, or 7th fret position. of course, use your ear...I could be wrong
