What type and size you need, and where you should point it. Does a large diaphragm do a better job in preventing pregnancy than a small? WTF is phantom power and why do you need it? All these important questions and more, discussed within. Entendre at your own risk.
Not that it matters but some mics are rather fugly. Some look great but may have something unattractive about them. I refer to the RODE NTA-2 which is an otherwise nice-looking piece but its feature/option panel is an eyesore IMO.
I'm cherry-picking here and I know it's pointless but my OCD cannot help but notice these things. I also hate green Les Pauls but that's another thread for ugly guitars.
I've got a Rode NT1 and it looks cool, completely smooth - not an ugly feature set on it.
LOL, Greg - I agree about the electric shaver.
D112 is pretty ugly - looks like a cooking utensil.
My NT2 has a much nicer looking set of switches - some of the front, some on the back - no weird panel. You do have to think about which way it's pointing however... which is, I guess, why they bundled them all together on the NT2A.
