You can play it with out a tremolo, but I REALLY recomend that you use one. Anyway, you just sway the tremolo back and forth, non-stop. You hammer the the notes with your left hand. On the open E's, grab the string with your thumb, and pull it down HARD. Then, bend your tremolo WAY down--as low as it will go to get a real raunchy sound. Les also put some kind of effects behind it, but you don't really need that either.
