Not entirely happy with the tab already here for the main riff, so here's my go.

E|-------------------------------------|
B|-------------------------------------|
G|-------------------------------------|
D|------------9-11-9-------------------|
A|-7h9--9h11--------11-9-7-----7-9-7---|
E|------------------------9-7-9--------|

The verse is all just open E on bass.

The keychange is exactly the same pattern but a fret higher, so -


E|-------------------------------------------|
B|-------------------------------------------|
G|-------------------------------------------|
D|------------10-12-10-----------------------|
A|-8h10--10h12--------12-10-8-------8-10-8---|
E|---------------------------10-8-10---------|

The last time he plays it he slows it down at the end.

The little chord played at the end is just

E|---
B|-8-
G|-8-
D|---
A|---
E|---

Cheers
