This is how it's played on the acoustic version of the song. The guitarist uses a 12 
string guitar but it's basically the same.

Capo on 5

C
Regrets collect like old friends
Here to relive your darkest moments
F
I can see no way, I can see no way
C
And all of the ghouls come out to play

Am          F                     C
And every demon wants his pound of flesh
              G                     Am
But I like to keep some things to myself
           F             Dm
I like to keep my issues strong
             F
It's always darkest before the dawn

C
And I've been a fool and I've been blind
                              F
I can never leave the past behind
I can see no way, I can see no way
C
I'm always dragging that horse around

Am               F                            C
And our love is passed, it's such a mournful sound
                   G                       Am
Tonight I'm gonna bury that horse in the ground
              F              Dm
So I like to keep my issues strong
                 F
But it's always darkest before the dawn

C
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaaah

F
And it's hard to dance with a devil on your back
              C
So shake him off, oh woah

Am    F                      C
I am done with my graceless heart
                      G                      Am
So tonight I'm gonna cut it out and then restart
                 F              Dm
Cause I like to keep my issues strong
             F
It's always darkest before the dawn

C
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaah

F
And it's hard to dance with a devil on your back
              C
So shake him off, oh woah

Am                             F
And it's hard to dance with a devil on your back
C                                  G
And given half the chance would I take any of it back
Am                          F
It's a final mess but it's left me so undone
Dm            F                C
It's always darkest before the dawn

C
Oh woah, oh woah...

Dm
And I'm damned if I do and I'm damned if I don't
Am                                     G
So here's to drinks in the dark at the end of my road
Dm
And I'm ready to suffer and I'm ready to hope
Am                           G
It's a shot in the dark and right at my throat
F
Cause looking for heaven, for the devil in me
Am                            G
Looking for heaven, for the devil in me
F
Well what the hell I'm gonna let it happen to me

C
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaah

F
And it's hard to dance with a devil on your back
C
So shake him off, oh woah

C
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaah

F
And it's hard to dance with a devil on your back
C
So shake him off, oh woah
