Hmmm...that is not a standard naming for the chord. b3 indicates a minor chord, not major. This chord would have the root, b3, 5th, and maj7th notes. A, C, E, G# .

A better name for it would be AminMaj7. It is the "harmonic" minor chord.

----------- ( E, 5th)
---1------- ( C, b3rd)
---1------- ( G#, maj7th)
---2------- ( E, 5th )
---0------- ( A, root )
---x------- ( mute or don't play, but could be played open E for another 5th)

(that's one way I would play it )

Peace,
