To me, "mastering engineer" does not mean "professional engineer" or someone who actually has a B.S. or Masters degree in Engineering.
It seems like practically anyone can be an "engineer" these days just because their job title says "engineer".
I mean does a recording engineer have a B.S. degree in Engineering?
I have a blue and white striped cap- am I an enjineer? I even went to an engineering school. I guess they took that name because they knew more about how to get certain sounds while recording. I would have to assume that some are actually engineers but they would normally show that in their name or title. BSME, BSEE, PE and any other discipline would probably raise a few eyebrows in the recording community and immediately brand whoever used it as arrogant.
The guy with the Tapco, isn't, IMO. His methodology was far from what I would expect from an engineer, and because of said engineering school history, he doesn't fit the mold.
