Here's what I did just last night at my friend's studio, helping my (possibly) new guitarist record some acoustic tracks...
Guitarist stood, playing an Epiphone acoustic guitar... Hooked up two mics... One was the studio's
Shure Prologue (hey... whatever..) mic, and the other was my trusty SM58... Track one on the board was the prologue, pointed to just behind the bridge on the guitar, about 6-10 inches away from it, probably closer to 6-8... Track two was the SM58, about 8-10 inches away, pointing downward at where the neck met the body, a hare towards the body, somewhat at a 45 from the guitar. Ran both into the board, similar EQ (forgot the exact settings), and equal amounts of signal, basically... Backed off the highs a little... And got the coolest acoustic sound I'd heard out of that studio, ever.
I was damned proud of myself... I read about that mic'ing situation somewhere on here... And it friggin' worked like a charm! Since it was just basically a scratch track, i didn't mess with fine-tuning it to the point of becoming anal about it, but it sounded nice without doing crap to the eq! Had plenty of lows (from the Prologue at the bridge) and the highs were bright and punchy without becoming overriding (from the SM58 at the neck joint). I was friggin' psyched!
I love this board! *LOL*
