It looked fake to me. He was using the same “chord shape” seemingly at random up and down the neck. At first I thought maybe it was an open tuning but after a bit I was thinking fake for sure.
He plays with the low E on the bottom like Dick Dale, Eric Gales, Doyle and Albert King and can play the guitar really well! Was it piped in like instruments are known to be during the superbowl? Idk, but he is an all around talented guy!
