If you are thinking of soldering a piezo disc directly to a guitar cable, stop and get some help. This is the help. It is a high fidelity piezo disc preamp on a circuit board. Put it between the disc and cable and you will get much better sound.
The core amplifier part of the circuit is the same as is in
Metal Marshmallow Pro, except this board is externally powered. It has super-low noise even at high gain. It has a proper high-impedance input buffer so that it has good bass response and you won't get that awful sound associated with pizeo discs soldered directly to guitar cables.
