I would have been interested to hear that. With tone in the fingers, their fingers are way better than mine. About the only interest I'd have of a piezo in a fretted instrument would be for the MIDI.
I don't know how to describe it, except to say that it had a dynamic life to the attack and decay that was definitely not magnetic. It sounded completely organic compared to the other two bass tones, and was very appealing to me.
