I was about to say "just because it's meant for use as a drum overhead, that doesn't mean it's not a good recording mic." Truthfully, the far-and-away most common use for the MK-012 is a cheap drum overhead. I use my C1000s as drum overheads.
...Then I looked at the frequency response graph. Ouch! This is gonna be a very colored mic, no? That big "presence boost" from 3k to 16k and -12dB "20hz" response explains why they recommend it for percussion and saxophone. I wonder about acoustic guitar or piano, though.
