So, I have a Beta 58A that has been intermittent. I have checked all I can see but I have a question.
I notice that early Beta 58 mics can be separated in two places easily by threading... One at the pop filter, and one at the "seam" part way down, the "A" version only seems to thread apart at the top, and the lower seam seems (no pun intended) to be only cosmetic to look like the earlier model.
True, or do I not know a secret?
