Hi,

Ive noticed many players play this chord and ivent been able to make out what it is ....perhaps its cuz they wrap their thumb over the top of the neck and all four fingers are on the guitar neck as if they are all barring frets they are on ....i at first tht it was probably a major ...like u play a B major on the second fret....but then again its the question of the position of the tumb and the other fingers ....Billie Joe...James Hetfield...Gilby Clarke....and a lot of others use this ...what chord is it ?

It's just a different method of forming chords. Personally I don't like it. But it works for some people.
Try using it with chords you already know. It works with pretty much any chord that needs a fret pushed down on the E string.
