  • Stringed instrument electronic pickup
    Patent number: 7319188
    Abstract: A piezo-electric sound pickup device for a stringed instrument having a wood or other shapeable material for a casing that is slightly larger than the standard gap between the wing and leg of the instrument bridge. The sound pickup device can be sanded to the proper dimension to properly fit this wing to leg gap. The installation of the pickup after proper sizing does not change the tone of the instrument and does not require further shim installation.
