90947C MODIFICATION DEVICE OR STRING INSTRUMENT PICKUP Abstract of the Disclosure A device that modifies the operating characteristics (e.g., amplitude, frequency response, "sustain") of the output signal of an electromagnetic pickup for a stringed musical instrument, such as a guitar with steel strings; the modification device comprises a thin, flat permanent magnet, preferably a sheet of resin impregnated with particulate permanent magnet material, that is magnetized transversely to its thin dimension. The permanent magnet covers most or all of the top or bottom surface of the electromagnetic pickup, usually the top. The signal modification device may include one or more mounting elements for mounting the permanent magnet sheet on a pickup, if intended for addition to an existing pickup. In the simplest form the mounting element(s) may comprise a rim on the permanent magnet or one or more steel plates mounted on the magnet; the steel plate or plates further may modify the output signal of the pickup. For a signal modification device that is to be incorporated in a new pickup, no mounting elements may be required.
