Nice song!!
He plays many ghost notes which makes it difficult to hear which notes are actually played, but at least I tried my best...
In the intro and verses he alternates between F#5, F#m and B. Occasionally he plays an open low E-string.
F#5: F#m: B: ...and the open E:
e--x----x---x----------x
B--x----x---4----------x
G--x----2---4----------x
D--4----4---4----------x
A--4----4---x----------x
E-(2)--(2)--x----------0
In the "bridge" leading to the chorus he's playing the F#m.
In the chorus itself the following chords appear:
A: G:
e-x---x
B-x---x
G-6---4
D-7---5
A-7---5
E-5---3
Then it's back to verse chords again, followed by bridge, chorus, verse, bridge, chorus, verse and an ending - containing the chords F#5 and F#m.
Guess that's all!
May still need to be corrected though...
