Too funny that I just registered on this forum and low and behold - my tiny little article has popped up.
A big vote for the ML52 (obviously). With the mods, it's a very good mic indeed. I use it often on guitar amps, and sometimes on drums.
For what it's worth, I've heard just as much variation between one 77 and the next as I have between ML52s. The best 77 still wipes out an Oktava, but as with any microphone, it depends on the application. There's no such thing as a useless mic, only a useless engineer.
