Thanks. Lots of good suggestions. I've been using a large diaphragm condeser and it tends to capture all of the low end boominess of a dreadnaught. For some reason microphones tend to want to capture that better than our ears do. I can EQ it but I'd rather pick up less of it in the first place because the EQ tends to get more heavy handed than I like. The Oktava looks like a nice, high-frequency oriented choice and it's available with interchangeable capsules. The specs look like it would be tailor made for recording a dread or a jumbo. I'll bet it would be almost scary on a banjo. Should be a super mic for cymbals and snares also, I would think. I'm familiar with the SM81 and I've used them before. I've always liked them. It always seemed as if there were no mic there at all. I've used them for micing horns and drums but I never tried one on an acoustic guitar. No particular reason. Should be a dandy product in that application. It is a classic to be sure. Thanks for the comments. I'll fuss with them and the specs and choose something.
