Hey. This is my tab for Am I Wrong by Brand New :). This song is very easy and can't be too hard to figure out.
I have tabbed this in Brand New's normal tuning of Eb Ab Db Gb Bb Eb . (All strings one semitone down)
I think this is the song generally, there's other stuff I couldn't figure out like piano and things. Just play these chords however you think sounds good. 

Please rate and correct :). Chris
