Apparently Sam has said at some point that this started as a Ghosts and Vodka song, and Tim played the bass on it. So I can only assume Sam is playing the left channel guitar.

Dunno the tuning. The natural harmonics sound right in this tuning though.

I believe this is as good of a tab as I can get. Most of the leads are isolable enough. I know a lot of them have borderline impossible fingerings, but they have noticeable chorus effects which made me think Victor plays the same note on different strings most of the time (though maybe he just uses a chorus pedal). Also it's Victor playing so maybe he actually can play it this way.

I am most unsure about the rhythm guitar. The chords are probably right, but I can't really tell the strumming pattern from the only MP3 of the song that seems to be in existence.
