Ok, the tab I read was a little off. Play this song quickly for it to sound right. Your guitar should be in normal tuning, not tuned down @ all. Sounds best w/ a distortion pedal of some kind. There is a lot more rythem to the song, if you'd like the rest or just a certain part, email me and I'd be glad to help. Enjoy!

Now, repeat that without the 2/12/2 slide and that’s it for
the first main part.
