Electromagnetic pickup for a stringed musical instrument having ferromagnetic strings and method
First Claim
1. An electromagnetic pickup, adapted for use with a stringed musical instrument in which the strings are formed of ferromagnetic material, comprisinga nonconductive, non-magnetic body having at least one hollow cavity,at least one conducting coil wound on an electrically nonconductive, non-magnetic core form,a flexible permanently magnetic bushing adjacent to and surrounding said coil,said coil and magnetic bushing being arranged within said body so that in use they will be disposed perpendicular to the surface of a plurality of the strings of said instrument, whereby said magnetic bushing provides permanent magnet means to direct a magnetic field into said coil and at least one of said strings.

Abstract
A pickup for an electrical instrument of the stringed type which comprises a pair of coil assemblies disposed within hollow magnetic bushings, the coils having its winding axis perpendicular to the strings, a hollow cylindrical shaped permanent magnet made of rubber-like plastic positioned around the outside circumference of each coil assembly, parallel to the winding axis of the coil. The direction of coil winding and magnet polarity around the first bobbin is opposite to that of the second bobbin. The magnets being disposed within the body of the pickup, said magnets serving as a sleeve for mounting coil assemblies and coil forms and suppresses microphonics by acting as a dampening means. A very dense and improved magnetic flux path passes from the inside surface of the hollow magnets through the coil assemblies disposed within said magnetic assemblies, said flux then sweeping the string area in a radial motion therein producing a novel tone having improved sustain qualties. The basic geometric shapes of the pickup components lend themselves well in regards to simplifying manufacturing procedure.
