This is the correct tab for the intro of this song.  If you dont believe me then listen to the song and play with it and you'll find out that is right.  AFI is a great band and their tabs dont need to be screwed up.  And yes this is supposed to be played on bass guitar but there are others out there that like to play bass tabs on the guitar.
