Hi there, I'm considering buying an AT4040 because from what I hear, it's said that it's a pretty neutral mic, and I'm looking for something that is not going ot emphasize the natural low mids in my voice... However, I look at the 4050 and it has different polar patterns... So, my question is this: Are the 4040 and 4050 different sounding mics, or is the difference in price between the two due to the polar patterns, cause then I'd be interested in a 4050... Any info appreciated, thanks...
