Ok, I hate doing a tab where its finger-picked cuz A: it's a pain in
the butt, and B: he may hit a couple different strings than what I put
here and there. Anyways I just tabbed this out real quick without
listening to the solo version I have so while it may not be exact, you
can get the gist.

Ok, to start out, make an open D shape, then take away the 2 on the
high e string. This is the basic shape that the intro/verse is made up
of. OK, now first, I'm just gonna tab out the main notes of the riff
that really stand out, then I'll do the full tab. Also the timing is
not indicated. Listen to a sound clip-preferably a solo one.

That's basically it. Again not every note in the Verse riff there is
exact(except for the ones I tabbed out at the very top) but it should
get ya started. Peace,   ~PJ
