open G tuning again, and again a capo on the 4th fret helps.

tabbing is relative to capo.

main riff:

--------------|
--------------|
-3--1--0------|
-3--1--0--0---|
-3--1--0--2---|
----------0---|

bridge:

simply an E repeated a few bars...

---
---
-5-
-5-
-5-
---

then chorus is...

-------------------------|
-0-0-0-0-0-0-0-0-0-0-0---|
-0-0-0-0-0-0-0-0-0-0-0---|    x2
-0-0-0-0-0-0-0-0-0-0-0---|
-0-0-0-0-0-5b6r5p3-0-3-0-|
-------------------------|

then...

-----------------------------------|
-0-0-0-0-0-0-0-0-0-3-3-3-3-3-3-3-3-|
-0-0-0-0-0-0-0-0-0-3-3-3-3-3-3-3-3-|
-0-0-0-0-0-0-0-0-0-3-3-3-3-3-3-3-3-|
-0-0-0-0-0-5b6r5p3-3-3-3-3-3-3-3-3-|
-----------------------------------|

other times this is replaced with...

-----------------------------------|
-0-0-0-0-0-0-0-0-0-3-3-3-3-5-5-5-5-|
-0-0-0-0-0-0-0-0-0-3-3-3-3-5-5-5-5-|
-0-0-0-0-0-0-0-0-0-3-3-3-3-5-5-5-5-|
-0-0-0-0-0-5b6r5p3-3-3-3-3-5-5-5-5-|
-----------------------------------|

and other times those two chords are switched round.

the break is slides around the twelth fret (8th from capo) and other notes i mean its 
to improvise right?
