    • Q:

      I'm looking to get my first pair of SDC mic's for acoustic guitar recording only and understand these were sold in pairs at one time. How much of an issue is it to have an unmatched pair of these? How do they compare to the 4041 or AE5100?

        A:

        Thank you for your inquiry. There is no need for a "matched" pair with the AT4021. Every mic is held through very tight tolerance, so each mic should be extremely close in spec and sound. The AT4021 is a hotter mic that the AT4021. Since the AE5100 is a large diaphragm mic it is hard to compare the two.
