This is the main part that goes throughout most of the song (it changes slightly as the
goes on though). Haven't found a tab for it elsewhere on the net and today I just
upon the melody as I was noodling. I always thought it sounded difficult, it's actually 
simple. The trick is in the open strings. When playing, use some overdrive or not a lot of
and a lot of chorus and reverb to sound like Duane Denison.
