dobro, the two mics were not used in the same manner by any means. John could have reversed the positioning of those mics and got quite different results. He could have mic'ed the piano with both mics from the same position and got very different results.
My comments earlier also should be considered. The AT could have sounded much better in another position.
Truely it is not what you have, it is how you use it. Play around with positioning two of your own microphones and you will see. That I believe is what John also said earlier was his point.
Good Day!
