I guess I have to say it over and over- this is NOT a taping gear question, as I stated in the FIRST FEW WORDS of my original post. It is a question about the history of this particular mic and how it was marketed, utilized and developed. I am simply asking for facts, not guesses, uninformed opinions or taping use information.
I appreciate the replies so far- but it's not what I'm looking for. If someone has actually owned one of these, or is familiar with it by direct association, that would be more useful. It is interesting to me because there appears to be no readily available information online for this particular model, and a number of experts in the field, including one active recording engineer, have never seen it. I appreciate the efforts but I cannot take guesses or "appears to be" as concrete fact. Unfortunately, these days, everyone is an "expert" on the internet and many offer information that has no factual base to it. You wouldn't want your physician to base your treatment on such "facts", would you? "yeah, it appears to be cancer, so let's go full bore chemo on it".......no thanks, lol.
So again, thanks for the replies so far, I do appreciate it, and please don't take my hesitation to accept them as fact as a personal insult- it isn't. I'm just a guy who wants to know the truth, not muddled, gray-area data. That said, no further replies are needed, I'll take this to the audiophile sites, perhaps they will have some first-hand knowledge of the mic.
