This is the main riff:

E|------------------------------------------------------------|
B|-7~-6~-4~-0~------------------------------------------------|
G|-------------6~-4~-3~-2/3~----------------------------------|often
D|------------------------------------------------------------|
A|------------------------------------------------------------|
E|------------------------------------------------------------|

Then he plays something different, nearly a slow solo:

E|------------11^12^11----------------------------------------|
B|--7~~-4~~-------------7^8-6^7-7^8-8^9-7^8-6^7-7^8-----------|
G|------------------------------------------------------------|
D|------------------------------------------------------------|
A|------------------------------------------------------------|
E|------------------------------------------------------------|

That's it. The rest are too much effects.
