Brian have you thought about using a mic element for the cone and a pup at the neck. Using the mic will get that reso sound that your looking for plus you`ll have the pup for the extra punch. The mic gets mounted on the bottom of the box below the cone. Ted used one already, I have them in my license plate double neck. They pick up the sound good but not as good as in the biscut, but they do give the build that old time reso sound.
