It's probably not 100% accurate, but since there is nothing tabbed for this as of yet here is what I came up with. I played the track Leave You With A Letter and figured this out on an acoustic guitar, I'd imagine it would sound way better with an electric but I like to learn by ear with my acoustic. I am also not good at tabbing and if this looks insane and you can't figure it out directly, I can post a sound clip of what it's supposed to sound like so you can follow it better. Hope it helps you a bit. Please take notice this was tabbed with my guitar in Standard Flat. Eb-Ab-Db-Gb-Bb-Eb.

EDIT:: When the "chorus" part starts, you do want to strum the opening chord ( F# with root on D-string 4th fret) once.
