Sorry, but you can't match the sound of a well mic'ed guitar in a good room (with good guitar player of'course)

What I currently do is using a Geffel condenser on 8-figure positioned about 15-20 cm from the neck joint, through a copy of Gyraf tube preamp and then a ShinyBox 23 ribbon mic for distant miking in variuos positions (probably 1 meter away or 30 cm above my shoulders or any other position that me finds sounds good ) depending on the sound I want. In most cases, where you need a solo acoustic sound I would just use the Geffel track.
