It's taken me almost a year to get the guitar and vocal sound I want in my recording....guess I've always been lucky to be around people who knew more than me.....the best advice I could give is to listen to people who know what they're talking about and experiment.....the advice above about the AKG Perception mics is a good one.....I'd go with the Perception 200's since they have a bass roll-off (very helpful with acoustic guitar).....mic that acoustic in stereo for a nice full audio image.....check out "spaced pair A" at this web sight http://www.humbuckermusic.com/acguitrectec.html good preamps will be very helpful....the Behringer mic-200's are inexpensive and quiet, and have great "valve" settings.....
