Hi guys! It's my first time posting here on Ultimate-Guitar so be nice!
Anyway, after watching live videos and listening to the song a lot of times I've 
finally figured out the chords that Brandon uses. 
Sounds about right to me, so enjoy! 
I've also figured 3/4 of Ryan's. I'll be posting that one soon :) 
Feel free to comment/critique/hate/something! :)
======================================================================

NOTE: Brandon usually silences/doesn't play the 'e' string.
      Just listen to the song for the strumming. So you'd know when to pause etc.
