No idea but will respond anyway so you know at least someone read the question.
piezo pickups fitted on a Guildstarfire II, along with the allready fitted pickups...
Pete Brown, the luthier who works on my guitars, has a highly-modified Guild Freshman with (I think) three pickups AND a piezo, and takes great delight in demonstrating the variations in tone he gets with the all the various permutations and combinations of pickups available to him.
So what do you want to achieve with such setup? Copy a Taylor T5 ? Sure, whatever you like can be done. But I am not sure how good of an acoustic guitar a Starfire II will be.

You know what, when you wrote "Starfire II" I was thinking about the Starfire II six string guitar, not the bass. I missed that this was in the bass discussion subforum.dunno, maybe expand the audio palette available to my bass... and since its already a semi-hollow the piezo might do the trick...
