Musicfan--
I've had a 3035 ($110 used) for a little while and just got a Rode NT3 ($100 new). The AT in comparison to, say, an SM58 is awesome. Clear and uncolored vocals. Not so great on acoustic guitar--not detailed. The NT3 is really something on guitar-crystal clear without ever being too bright, and pretty nice on the voices I've tried it on. Better defintion on the vocals, compared to the 3035, with as solid a bottom, but I don't know which I like better yet. I just record with my friends in my house, so understand this isn't a pro comparison. The only other large diaphragm I've tried is an Oktava 319, which I sent back after a day. Digital recordings sounded like a cassette without Dolby, it was so noisy.
Zbert-
Could you say a little more about how the sounds of the 3035 and 4033 differ?
