I really hate it when people set rules, never break them, and then promote them as somehow the only or best way to do things. Before I make decisions, I use my ears. What something sounds like provides everything I need to make a sensible guess, then perhaps try an alternative. It would be stupid to make crazy rules - like blondes need condensers, but brunettes need dynamics, and if you have a beard, then you must use an omni, but if you have no hair at all, you really should record in M/S, with a ribbon. Seriously folks - this is what is being promoted. Rigid ridiculous rules are everywhere now. We should stop this as i just gets promoted as fact by the newcomers, who assume forum comments are always accurate. Right mic for the right job - which one? Depends on your mic box!
