It is also valid to mic closer , say 4-6", with either mic alone. I put it where the neck meets the body, and then move toward the headstock, one fret at a time. I've gotten very good results that way with AKG C414B. The Oktavas I occasionally use backed off, say 3 feet, as an X-Y coincedent stereo pair. Try the Oktava close on the 12th fret with the AT mic looking down at the body over your shoulder, and reverse the phase on the AT.
One question- Does your Taylor have a Fishman Prefix Plus in it? They use a couple of different Fishman units. The Prefix Plus is a stereo blender. It has an undersaddle piezo pickup, and a back electret mic also. It has stereo output, so you can separate the 2 signals. I've gotten excellent results DI with my Taylor, separating the 2 signals into the 2 sides of a dual-channel preamp. It works especially well with
my Joemeek twinQ. The weird part is, the mic sucks, and so does the pickup. But, if you start with a fair amount of the mic, then start gradually adding pickup, eventually you come to a sweet spot where I'll be damned if it doesn't sound like a guitar mic'd up pretty. This works both for recording, or as a mono output for stage use. Try plugging it into a Strawberry Blonde acoustic amp sometime. If I had a Taylor with any other Fishman system, I'd consider paying to have a Prefix Plus installed in it. Best of luck.-Richie
