intro riff-

  guitar 1 (distortion)
E|------------------------------------|
B|------------------------------------|
G|------------------------------------|
D|--5--3----------3--3-----2--2-------|
A|--------5-5-------------------------|
E|-------------3--------3---------3---| repeat

I find it easiest to use my thumb when playing the lower notes.

 (pay more attention to the rhythm and the feel than to the numbers)
E|------------------------------------------------3-|
B|------------------------------------------------3-|
G|------------------------------------------------4-|
D|-5-7--5-7---5-7--5-7---7-9--7-9--3-3-x-4-4-x-5--5-|
A|-3-3--3-3---3-3--3-3---5-5--5-5--3-3-x-4-4-x-5----|
E|---------------------------------1-1-x-2-2-x-3----|

  guitar 2 (right before verse)
E|---------------------|
B|----------3--0-------|
G|---0--3b--------3----|

  verse/main riff-

D|-------------------------5-5-7-5-7--5-5-7-5-7--|
A|---5-5-7-5-7--5-5-7-5-7--3-3-3-3-3--3-3-3-3-3--|
E|---3-3-3-3-3--3-3-3-3-3------------------------|

G|------------------------|
D|--7-7-9-7-9--3---4---5--|
A|--5-5-5-5-5--3---4---5--|
E|-------------1---2---3--| continue similar pattern

  Then there are a bunch of chords that I don't feel like figuring out right now
  and this lick right before the harmonica solo:

E|---3------------------------------|
B|---3------------------------------|
G|---4---------------------------3--|
D|---5---------------------3--5-----|
A|---5------------3--4--5-----------|
E|---3------3--6--------------------|

  After the harmonica solo the rhythm guitar goes into this riff:

E|----------------------------------------------------|
B|----------------------------------------------------|
G|-------------------------------5-0-7-5----7-5-------|
D|---5---7-7-----5---7-7----5----5-0-7-5--0-7-5-0-5-7-|
A|-0-5-0-7-7---0-5-0-7-7--0-5-0--3-0-5-3--0-5-3-0-5-7-|
E|-0-3-0-5-5---0-3-0-5-5--0-3-0-------------------3-5-|

  During this part, the other guitar plays something like this:
E|------------------------------------|
B|------------------------------------|
G|------------------------------------|
D|--------7-------------7-------------|
A|------------------------------------|
E|------------------------------------|

  Follow the tab here loosely. Just play it in rhythm and it should sound alright:
  (Palm mute)
       bend it when it sounds appropriate
E|-----------------------------------------|
B|-----------------------------------------|
G|---5-7-7b-7-7-7-7-7-7-7-7-7-7-7-7-7-7r-5-|
D|-7---------------------------------------|
A|-----------------------------------------|
E|-----------------------------------------|

E|----------------------------|
B|----------------------------|
G|-5-7-5--5-7-5-5-7-5-5-------|
D|----------------------5-7---|
A|----------------------------|
E|----------------------------|
