Abstract:
1. A magnetic pickup for generating an electronic signal in response to string vibrations in a musical instrument, the pickup comprising: two self-contained string-sensing pole pieces, at least one of the two pole pieces comprising first and second discrete ferromagnetic components in fixed relative positions, the first ferromagnetic component being formed from a material in a group consisting of cast alnico alloys, sintered alnico alloys, bonded hard ferromagnetic materials, flexible hard ferromagnetic materials and machinable hard ferromagnetic materials, and the second ferromagnetic component having properties that are different from ferromagnetic material properties of the first ferromagnetic component; a wire coil that at least partially surrounds the pole pieces; and a mount that holds the pole pieces in a fixed and nonadjustable position with respect to the wire coil and secures the pole pieces to the musical instrument.
