The general consensus is to spend some money on a few more mic's. Maybe another AT4050? Stereo mic'ing with a pair of AT 4050's might be the ticket.
I just want to have nice full bodied sounding acoustic tracks with definition across all the frequencies.
Stereo micing a guitar isn't easy and you can run into phasing issues, so be sure your preamps can change polarity. One mic is all you need to achieve a full bodied and defined sound -- but placement is key.
Still, I'd get some more mics in any event -- perhaps the AT4050 as one for a stereo pair on other applications... Perhaps one really great mic on top!
