INTRO:

... put some 'wah' on and just slowly play something like this and let all ring out ... 
or just make some noise^^ ...

E|-0--------------------------------------------------|
B|-0--------------------------------------------------|
G|-x---------0--2--3--0-------0--2--3--0--------------|
D|-2--------------------------------------------------|
A|-2--------------------------------------------------|
E|-0--------------------------------------------------|

Then without 'wah' the MAIN RIFF (distorted):

E|-----------------------------------------------------|
B|-----------------------------------------------------|
G|------0--2--0-2-3-0----------------------------------|
D|-2----0--2-------------------------------------------|
A|-2----x--0-------------------------------------------|
E|-0----3b---------------------------------------------|


Listen to the song for the rhythm and play it dirty, sloppy and with passion!
It's rock'n'roll, guys!


Main riff- Variations:


E|-----------------------------------------------------|
B|-----------------------------------------------------|
G|------0--2-------------------------------------------|
D|-2----0--2-------------------------------------------|
A|-2----x--0--5h7-7-5----------------------------------|
E|-0----3b---------------------------------------------|


Grohl is playing something like the melody when Shifflett is doing the background vocal thing.
Not sure about this though:

E|-----------------------------------------------------|
B|-----------------------------------------------------|
G|-12---11----9----7--------(0-2-3-0)------------------|
D|--x----x----x----x-----------------------------------|
A|-10----9----7----5-----------------------------------|
E|-----------------------------------------------------|


Later in the song this is also played once within a main riff section:

E|-----------------------------------------------------|
B|-----------------------------------------------------|
G|-------------10/12-12\----------------12/14-14\------|
D|-2----8--10--10/12-12\----2----10-12--12/14-14\------|
A|-2----8--10--8-/10-10\----2----10-12--10/12-12\------|
E|-0----6--8----------------0----8--10-----------------|

E|---------------------------------------------------------------------|



VERSE:


The verse is just the main riff played clean, or what I like to play:

E|-----------------------------------------------------|
B|-----------------------------------------------------|
G|------0--2----0-2-2-0--------------------------------|
D|-2----0--2----0-2-2-0--------------------------------|
A|-2----x--0----x-0-0-x--------------------------------|
E|-0----3b------3-----3--------------------------------|


Sometimes a distorted guitar will play some chord or bits of the riff simultaniously. 
Quite randomly though.

E|---------------------------------------------------------------------|



PDC HORUS:


 |still the verse| DISTORTION!
E|----------------|-------------------------------------|
B|----------------|-------------------------------------|
G|------0--2------|--7-9-9-9----------------------------|
D|-2----0--2------|--7-9-9-9----------------------------|
A|-2----x--0------|--5-7-7-7----------------------------|
E|-0----3---------|-------------------------------------|


Just downstrokes:

         "Miss the misery ..."
E|------------------------------------------------------------------|
B|------------------------------------------------------------------|
G|------------------------------------------------------------------|
D|-5-5-5-5-5-5-5-5-7-7-7-7-7-7-7-7-9-9-9-9-9-9-9-9-4-4-4-4-4-4-4-4--|

A|-3-3-3-3-3-3-3-3-5-5-5-5-5-5-5-5-7-7-7-7-7-7-7-7-9--9--9--9--10-10-10/12--|
E|--------------------------------------------------------------------------|


This is also played once in a different rhythm ... listen to the song, it's not too hard 
to figure out.

like this:

  D U D  D D  D D D D  D U D  D D D D D D
E|------------------------------------------|
B|------------------------------------------|
G|------------------------------------------|
D|-5-5-5--5-5--7-7-7-7--9-9-9--9-9-4-4-4-4--|
A|-3-3-3--3-3--5-5-5-5--7-7-7--7-7-2-2-2-2--|
E|------------------------------------------|
         |dont   let|       |these downs ring out|

Hope that helps.

E|---------------------------------------------------------------------|

LEAD GUITAR:

This is played over the last prechorus and the last chorus.


E|-12----12----12-----12-----14----14----14----14------|
B|----12----12----12-----12-----12----12----12----12---|
G|-----------------------------------------------------|
D|-----------------------------------------------------|
A|-----------------------------------------------------|
E|-----------------------------------------------------|

E|-12----12----12-----12-----11----11----11----11------|
B|----12----12----12-----12-----12----12----12----12---|
G|-----------------------------------------------------|
D|-----------------------------------------------------|
A|-----------------------------------------------------|
E|-----------------------------------------------------|

E|-12----12----12-----12-----14----14----14----14------|
B|----12----12----12-----12-----12----12----12----12---|
G|-----------------------------------------------------|
D|-----------------------------------------------------|
A|-----------------------------------------------------|
E|-----------------------------------------------------|

before going back to the main riff I tend to play the last bit just like:

E|-12----12----12-----12-----14-14-14-14-14-14-14-14---|
B|----12----12----12-----12--12-12-12-12-12-12-12-12---|
G|-----------------------------------------------------|
D|-----------------------------------------------------|
A|-----------------------------------------------------|
E|-----------------------------------------------------|


That's about it I think.
Comments and improvements are welcome.
Enjoy!
(So far, my favorite song of the new record)
