They have the same damn model numbers, too, except with an "s" where the "g" used to be. If the ST55 is not the exact same thing as the GT55 (which I own) they sure as hell went to a lot of trouble to make it LOOK the same. Is the GT55 such a legendary icon of recording lore that other manufacturers are trying to duplicate it? I mean, it's a nice mic and all, but let's face it, it's not a u87.
