  • Noise sensing bobbin-coil assembly for amplified stringed musical instrument pickups
    Patent number: 7189916
    Abstract: A noise sensing bobbin-coil assembly for use in conjunction with a musical instrument pickup is disclosed. In particular, the bobbin of the bobbin-coil assembly is adapted to resist induced eddy currents thereby allowing a fewer number of coils to be used which in turn reduces undesirable interaction with the musical instrument pickup.
    Type: Grant

  • Transducer for a stringed musical instrument
    Patent number: 6103966
    Abstract: A transducer for a stringed instrument comprises a first uppermost coil and a second lowermost coil with the axes of the coils coincident. Permanent magnet pole pieces are arranged in the first coil and metallic non-magnetized pole pieces are arranged in the second coil. Oppositely directed U-shaped shields each having a web and outwardly directed opposed flanges are arranged back to back and receive the coils to shield the coils from each other both magnetically and inductively.
