Mac is tuned (as usual) slightly above a regular E tuning. Capo 3rd fret Here are the main licks he is using, but he loves to play around, remove a finger here and there. Follow your guts on that. Let ring all the notes he plays by themselves.

The layers of electric guitar are just the chords done in the chorus with a volume pedal, an auto-pan and delay. For the effects part, he only uses some reverb. Have fun, glad to see more acoustic guitar in his songs.
