Abstract: An electromagnetic pickup adapted to be secured to a stringed musical instrument, such as a guitar or bass or the like, of the type having a plurality of magnetic strings of ferromagnetic composition such as steel tensioned to provide musical notes under mechanical stimulation such as picking is disclosed. The electromagnetic pickup comprises at least one magnetized core having a length and a width. An electrically conductive material is wound into at least one coil around the magnetized core, and a ferromagnetic material such as iron, nickel, cobalt or alloys thereof is positioned on at least one side of the length and internally of at least a portion of the electrically conductive material. The electromagnetic pickup is mounted proximate the strings in such a manner that magnetic field of the pickup extends to the strings for the purpose of generating an output electrical signal analogous to the musical notes.

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.
