If you are going for an under nut transducer, I would recommend going with a polycarbonate nut expecially if you are intending on picking up "ghosting". Keep in mind a piezo only works correctly if the downward pressure is even on the element. Piezos were originally discovered when Oriental acupuncturists found a squared quartz crystal was producing too high and painful electrical offcharge. So they ground the crystals cylindrical... That is what I am currently working on. I talked to Rick Turner (Alembic)(D-Tar) Seymour Duncan, R. Neve, etc. etc. and he told me he thought of this concept years ago when he was sitting on the toilet reading a popular science magazine about under sea cable microphones. They trail them from submarines and the like to eavesdrop, picking up enemy protocol preparing them for a course of action! So there is your pressure explanation of how a piezo works aka: The Sea and Ocean waters tremendous pressures per sq. inch. Pressure exerted by percussive/succussive forces generates electricity. If you ever want to get a cheap thrill rub a quartz crystal or agate on a sidewalk or sandpaper in the dark!!! Awesome electrical aurora produced. Hope this information helps... Rick and Roberto-Venn School of Luthiery will have all the information you could possibly imagine and keep you from goin on any wild goose chases... Daniel T.
