I just got a new 4050 the other day, and am impressed with it so far. I've given it a few runs on vocal duties with various kinds of performances and I guess you could say right now I'm in the middle of getting acquainted with it....learning when and where I like it. It hasn't sounded "bad" yet, and it was quite a bit better (to my ears) than all my other vocal mics on one song. It's my first multi-pattern LDC btw...I usually track vox with an sm7/sm58/tlm102. I also tried it on acoustic guitar today, and liked it much better than my usual mic on that duty (4033). With all that said, I can't stop being curious about the AKG c414.....the ULS/XLS version, that is. The reason I purchased the 4050 instead is that I only had around $600 to work with, and it came down to buying a new 4050 that I could return if unimpressed, or a used 414 that I would have to resell. So I went the safer route. I've read that the 414 has a nice, full bottom end (as does the 4050) and also that it's freq response is fairly flat. So with all that being said, I guess the main question I have regarding the 414 is it's fidelity in comparison with the 4050. In that regard, is the 414 a better mic?...a step up? Or are they similar in that department? If it matters, the only instruments I record acoustically are vocals (male tenor) and my Martin 000.
