None of the tabs up now have the right part for the intro, so here's the correct 
version. Standard tuning, listen to the song for the rhythm.

e|-----------------------------------------|
B|------1-----0----------------------------|
G|----------0---2--------2--------2-2------|
D|----2------------------------------------|
A|--0---------------------------3----------|
E|--------0-----1--------1----1-----3------|

That's the main guitar riff throughout the song.
