Been listening to this song a lot and thought I'd try my hand at it. It's a cool song with a great groove and not too hard to play once you get into it. It's in standard tuning but tuned down a bit. Playing out of E but he omits the B7 chord and instead plays notes up the neck that follow his vocal melody, I think he uses double stops extensively in this song to fatten up the melody. I have taken minor artistic liberties with the the song but mostly cleave to the original.
