much more interesting,
to simply track ANOTHER acoustic guitar track, played as closely to the original as possible, and hard pan those two.
and even better still, use two different guitars, and two different mics.
added bonus...
hold your lip different win you play the second track.
point is, you want ear candy, not homogenous swiss cheese.
if you want to experiment, try copying the mono guitar track to another track, and then time-line SHIFT the copied track back about 10 milliseconds.
then, add a mono reverb to an FX buss, and send the original acoustic track to the reverb, and pan THAT reverb send hard opposite of the original dry guitar track.
put the pre-delay on the reverb at the same 10ms, and put about 1.5 seconds on the reverb. a nice hall will do.
roll off a lot of the high end on the reverb.
don't mix the reverb send in, until AFTER you have mixed the two acoustic tracks in together, and have the EQ balance correct between them.
