Here is my Lee guitar story. So I was listening to Waiting on a Dream and I noticed that I heard what I thought was a bum note:

you can hear it at 0:07 and 0:14 above. I was pretty perplexed by this because it is not like Lee would make a mistake on a major recording. So this past weekend I am watching and it turns out he uses a whammy bar instead of it being a bent note.
Problem solved and understood.
