Great mic, great price

I use this for orchestral recording and get good results. AT does not offer matched pair, but they are well matched despite I received mics that have serial no. of 263 & 1454.

Great mic at a great price

I run a small project studio and am lucky enough to have a well-stocked micrphone locker. I'd heard many good things about the AT4021, and when I saw B&H's amazingly low price, I bought one. I immediately set about comparing this small-diameter cardiod (SDC) mic to some world-class competition: An AKG 451B, a Microtech-Gefell M295 and a Beyerdynamic MC930. Even though the 4021 didn't have the amazing clarity or 3D presence of the M295 (my favorite mic for recording large-bodied acoustic guitars and such), it had about 85% of the sound quality, for 1/7th the price! That's a terrific deal in my book. I think anyone with a decent recording setup will realize stellar results from this mic. At B&H's great price, I'd recommend buying TWO AT4021's and using them to record in stereo.
