Many of my instruments are amplified using piezoelectric technology, including the
Old Crapper,
Jamplifier, and of course the
Piezoelectric Banjo.
Wikipedia defines piezoelectricity as "A charge that accumulates in certain solid materials (notably crystals,
certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical
strain. The word piezoelectricity means electricity resulting from pressure."
Jugtones defines piezoelectricity as "A way of amplifying homemade instruments acoustically for free."
Piezo transducers are used in a wide
variety of applications
and are therefore easy to find & salvage for pickup adaptation. They are also very inexpensive to purchase if
you know where to look. Check out the PDF
"Piezo Sandwich Bridge"
for a step-by-step guide (with photos) of the making of the
Old Crapper's piezo bridge pickup.
