very interesting stuff there..... to answer your question... mainly vocals, maybe an acoustic guitar. I would like to stay around the $200 mark
how about these:
MXLor
MXL Yes, I have gotten very good results from both of those mic packages. In fact I have 2 of the 990/991 packages and I use the 991s as a stereo pair in overheads.
Now understand that these mics are NOT gonna sound like a Telefunken or Neumann but with care and proper mic techniques, they can get you some very good results.
You won't get hurt at the price, believe me.
