The intro/main riff is super simple and has a sweet groove to it that is
jarred by the drums.

g-------------5-------------|
d-0--3---5/7-----3~---------| strong vibrato on the last note

This is pretty much the whole song for lead guitar.... there are minor
variations... when the delay is off dean plays something like this:
e---------------------------|
b---------------------------|
g--------------------5------|
d-0--3-3-3------5/7-----3~--| strong vibrato on the last note
a---------------------------|
e---------------------------|


As for the solo its in the key of D and as far as i can tell is played over
the Minor Pentatonic main box at the 10th fret.
Seems like it begins with something around the lines of this:

e----------------------------|
b----------------------------|
g----12b14r12--10h12p10------|
d------------------------12~-|
a----------------------------|
e----------------------------|

Theres a lick something like this in there:
e-----------------------10~--|
b----------------------------|
g-----12b14r12p10------------|
d------------------12--------|
a----------------------------|
e----------------------------|

e--------------------------------------------------------|
b---------------------13~--------------------------------|
g-----12b14r12p10------------12b14r12p10-------10~-------|
d------------------12----------------------12------12~---|
a--------------------------------------------------------|
e--------------------------------------------------------|

now go figure the whole solo out people!

b - bend
r - release
h - hammer on
p - pull off
~ - vibrato

As jack white said in an interview with Dazed and Confused Magazine: "We're
all playing the blues. if you dont realise that....you're lying to yourself"
