by the way, the Fishman matrix is also a good pick-up, but would require and a bit of wood work to install. I use a Rare Earth in my Santa Cruz 000. I bought it because I did not want to cut the guitar, but I have been very very happy with the sound.

Fishman also makes a Rare Earth blender pick up, which uses a condesnor mic in addition to the mageneic pick-up. I suspect you'd be happy with out the mic, but that may depend upon your applictaion.
