Received the Rode NT4 Stereo mic from My Gear Guy in the mail today. Will give it a test drive tomorrow. Recorded the water rushing in the arroyo below my house with the new SD722 and a couple of Neumann KM-100s a few days ago and it sounded fantastic. The NT4 would be nice for travel sounds, since I would only have to carry one microphone.
I do think I will need a couple of mics with larger diaphragms to record my guitar and I will compare my AKG-414s and Shure KSM44s, since there is no way I will travel with my M149s.
