They're not remaking a classic; they're making a new mic, inspired by a classic. Kinda like a movie that was "inspired by real events" but has very little to do with actual history, even if it is reminiscent of actual history.
Maybe someone who's used a FET47 said, "You know, I like this mic, but I'm ALWAYS turning the high-shelf up a little bit. I'd love to have this same mic, but brighter." Or maybe they just said, "Hey, everyone loves the FET47, so let's say our FET mic sounds like one, but give it better HF response to make it sound more 'modern' and 'wow'!" I guess the last one is more likely. =)
Larry, that's an interesting thought. I guess that could very well be what happened.
I need to find me a better kick drum mic. What do y'all use that doesn't break the bank? (read: around $500 or less)
