havent tried the 4060, but the 4050 is my go to mic for vocals.
and im sure the 4060 isnt a pro-sumer mic, they 4050's are definitely reputable (at $599) and many people use them exclusively for vocals.
im sure you would be pleased if you got that 4060, the sweetwater page makes me wana get one lol.
although, i would also consider a 4047, they have a little peak in the 5k area while the 4050 has a slight dip, check out the frequency responses at audio technicas website. there is 2 versions of the 4047, and the multi pattern one has a bigger peak at around 5k than the un switchable cardioid pattern one. and if your recording vocals, around 5k is where alot of the presence is brought out in them. i myself have never used a 4047, but have heard that some people like them more for vocal recordings. just something to keep in mind.
although i did just look at the frequency response chart for the 4060 and it has an even bigger peak in the 5k range.
id go with that one if you can get a good deal on it.
