  How would one go about adding more strings to the guitar design? Will only one piezo element be needed?

  You would need one piezo per string, since each string rests on a piezo (with a sliver of a rubber stopper in between). This would produce a separate audio output for each string, which can be mixed together, or processed separately for interesting effect (called a polyphonic pickup). Tell me what you learn from building a PVC guitar with several strings.

  Any diameter will work. I use 1.5" for guitar, 2" for bass, and 4" for stand up base (6 foot tall!). EdV is correct. It's the piezo that picks up the sound. The pvc is there to hold the string. Same goes for the pine wood body-- it's just to hold it together, although ergonomics does prefer certain shapes.

  Will the diameter of the PVC have any affect on the sound of the guitar? Can I use 2" PVC instead of 1 1/2 " PVC?

  I am guessing 2" will work just fine. the sound of this guitar is going to rely primarily on the the string's contact with the piezo pickup.
