E|-2-2-2-2-2-2-2----|

He then does some other overdriven stuff, before he gets to the
lead in:

E|-15| H17-17-17-17--17-17-15H17-17-17-17-------------------------|
B|-15| H17-17-17-17--17-17-15H17-17-17-17-------------------------|
G|--------------------------------------------------------------|
D|--------------------------------------------------------------|
A|--------------------------------------------------------------|
E|--------------------------------------------------------------|

Then he gets to the main riff:

E|-12----12~-10----10~-8----8~-7---7~-5---5~-3---3~-------------|
B|----13--------12-------10------8------6------5----0-4-5~------|
G|--------------------------------------------------------------|
D|--------------------------------------------------------------|
A|--------------------------------------------------------------|
E|--------------------------------------------------------------|

There's another version of this riff which he does later:
(Tremelo pick this)

E|-12-12-12-12-8-8-8-8-10-10-10-10-7-7-7-7-8-8-8-8-5-5-5-5------|
B|--------------------------------------------------------------|
G|--------------------------------------------------------------|
D|--------------------------------------------------------------|
A|--------------------------------------------------------------|
E|--------------------------------------------------------------|

E|-7-7-7-7-3-3-3-3-5-5-5-5-1-1-1-1-3-3-3-3-0-0-0-0--------------|
B|-------------------------------------------------0-0-0-0-4-5--|
G|--------------------------------------------------------------|
D|--------------------------------------------------------------|
A|--------------------------------------------------------------|
E|--------------------------------------------------------------|

And right after that he does an insane version, which I can't figure
out.. I think it starts like:

E|-12------12------10-------------------------------------------|
B|----10-8----10-8----8-7--a| nd so on----------------------------|
G|--------------------------------------------------------------|
D|--------------------------------------------------------------|
A|--------------------------------------------------------------|
E|--------------------------------------------------------------|
