Topic: HDSPe AIO with acoustic guitar

Hi All
I have the 9632 HDSPe AIO with the balanced breakout cable, I've also have POD HD500 guitar interface.
I'm using the POD interface which has a mic input and plug my Shure sm57 and then rout to the soundcard. the signal is still low and the guitar sound is lack of clarity, my question is:
would a mic pre-amp will do a better job from my POD interface?
