Try it slowly at first, dont try to keep pace, cause if you cant do it slow, chances are you wont be able to do it fast.

Use the correct fingerings. It will probably just mess you up, espcially on that intro.

For the main solo, when i learned it, i listen to it alot. Trying to feel every note. Since theirs bends all over the place, halfs and full work on those, its will make or break the sound.

The outro ( where the pick scrapes are going on)you can either adlib, or do it as it is. All i can really say is pratice it, til you know it by heart.
