Guitar chord is cited as a chord in Kenny Wayne Sheppard's Born With a Broken Heart.
so, this chord is the 4 inside open strings? Whatever this "chord" would be called, if a chord at all, would have to do with the musical context in which it occurs.
The song you mention is a 12 bar blues in A flat. Where you got this chord from, I don't know. Some weird tab or other. It makes no sense in the context of this song. It looks like a mistake.
