It's just an A chord, the notes are A, A, C#, E. I guess you can call it an A with an A i the bass?

Keep in mind, a regular A chords 3 notes are E, A, C#.

In order, an A chord are the following notes; A, E, A, C#, e.

If that doesnt make any sense, too bad I suck at explaining. It seems to me just like a simple A chord, although a variant. I could be wrong though!

Well the xx765x is an A chord also, same notes just not in order.

x07650 sounds good, it's the first chord in Dandelion by Audioslave.
