I won't bore anybody again with another "best mic for under $200" thread, but I'm curious to find out how you go about deciding which mic to use for which particular application... I understand that large diaphragm mics are often better for vocals, but what about other acoustic instruments? Most of the stuff I've read so far has pointed to small d. condensers for instrument applications, and yet most acoustic bassists I know seem to prefer LD mics in the studio. Is there a reason you would prefer a SD condenser over a LD for piano or double bass?
Also, I've done enough reading to understand (I think) what the different polar patterns are, but how do you make that choice when it comes time to record? Is there a FAQ on this subject that I could read up on, or some links to some other sources to study? Any/all opinions welcome.
P.S. - I'm not trying to be a pest...I have actually been scouring the archives for the past few days on this subject, but would like personal opinions as well.
