Idea For Acoustic Pickup Combo

[Redhat]

Has anyone tried this?

I'm thinking of using reflective object sensors to detect string vibration, and combine it with a piezo to detect soundboard vibrations. My thinking is this would provide a very close approximation of the natural sound of an acoustic guitar, if I can get it to work.

Has anyone tried to use reflective object sensors here? Any input would be appreciated.

Thanks in advance.
