proof is in the pudding...
Well... If you won't take Harvey's word for it (God knows why you wouldn't.... you'll see for yourself how knowledgeable he is if you go find "The big thread"), then here is something I just recorded for the purpose of this thread.
It's an intermediate level acoustic guitar (
Norman B20) with old strings. I miked up a pair of ECM8000's in an XY configuration (sort of, anyway... capsules about 2 inches apart, a little less than 90 degree angle) pointing roughly at the 12th fret. Both mics were plugged into
my Behringer MX802A mixer (yes...

), and directly to my Delta 44 soundcard into Cubase. There was NO EQ, NO compression, NO effects/signal processing going into Cubase. Once recorded and playing back, I was wishing that I had engaged the Lo cut on the mixer, but I didn't, so I applied only enough EQ to roll off the low frequencies below about 100hz. Nothing else... completely raw.
In retrospect, I should have placed the mics a little lower so that they were angled more toward the top strings than the bottom so as to reduce the "boominess" a bit more naturally... oh, welll...
It's one take (there are mistakes in it), and it's short - about 44 sec. and about a half a meg as mp3.
I don't hear any excessive hiss... do you?
