First off....I've seen this mic called the MC012 and the MK012...no difference in the mic. Alright, I have used these mics as my OH's, on acoustic guitar, and on violins. I've found someone wanting to buy these from me, and now have a little dough to spend on "better" overheads. I've been looking at the matched Rode NT5's and the SP C4's. I'm not sure if there are many other options in this price range that will give me a versatile and all around good mic. What do you guys think? How do the NT5's stack up against the C4's, and is there anything else worth looking into?
