I own both mikes. Unfortunately, I've only had
my NT1000 for a couple of weeks and I was on vacation for one of those weeks. I have used it in a few recordings and I am very impressed so far. I haven't used it for vocals yet because I'm not a singer. It sounds every bit as good as my 4033 on acoustic steel-string and nylon string guitars, shaker, and tambourine. That's all I've used it for, and it was excellent on all those sources.
They both sound bright to me, but the 4033 seems to have a little bit bigger proximity effect and bass response. The NT1000 is really solid and heavy, and it requires a good stand. I was amazed when I took it out of the box how good the build quality seems. It's a beautiful looking mic. I can already say that for tambourine, which is a tough instrument to record well, I will reach for the NT1000 next time.....it sounded very natural. For clean electric guitar I love the 4033, although I usually record with amp simulations. On acoustic guitars I will have to spend more time with both mikes. My recordings show them to be very good for that application and allow my guitars to shine. I've owned my 4033 for 1.5 years so I know what it's going to sound like and exactly where to place it.
Tough decision. I don't think you could go wrong with either mic. Sorry I can't tell you which I like better for vocals. If you buy the NT1000, the best price I found was at
www.bpmmusic.com $259 for the mic, $39 for the shockmount, and free shipping.
