This is really easy, so I've tabbed it quite roughly. Great song though.
Intro
F to F# inversions- something like this.
E|--------------|
B|--------------|
G|--------------|
D|--3--4--3--4--|
A|--4--4--4--4--|
E|--1--2--1--2--|
Main Riff
E|--------------------------|
B|-----2-----2--------7-----|
G|-----------------8-----8--|
D|--4-----4-----9-----------|
A|--------------------------|
E|--------------------------|

Then it adds this to the ends of the chorus' and the intro is the chorus after the weird
F to F# chords (basically goes up to C#)
E|-----------------------------|
B|--------7-------------9------|
G|-----8-----8------10-----10--|
D|--9-----------11-------------|
A|-----------------------------|
E|-----------------------------|
2nd verse just plays F# B over and over
Chorus (same as the first)
Solo
Start on low F# to begin with, then play a chromatic scale up to a high F#. Then its
this played a few times.
E|-----------------------------------|
B|-----------------------------------|
G|--4--3--1--3--4--4--4--3--1--3--3--|
D|-----------------------------------|
A|-----------------------------------|
E|-----------------------------------|
Then it goes to another chorus, then the outro (where it changes) is
F# B C#, then finishes on F#
Thanks, cant wait for their album in March.
