When looking at the use of piezo elements as pickups in acoustic instruments, and specifically in cigar box guitars, there are two main types that get used – disk-style piezos, and rod-style piezos
While disk piezos are perhaps more prevalent, because they tend to be cheaper and easier to find, many builders feel that the rod-style piezos offer superior sound and tonal quality. This article delves into the differences between disk and rod-style piezos, and takes a close look at how rod piezos are put together.
First, a little bit of piezo basics. Piezoelectric elements, whatever the type, are based around layered ceramic wafers and conductive metal. Continue reading “Rod Piezo Primer”
