ELECTROMAGNETIC PICKUP FOR STRINGED MUSICAL INSTRUMENTS - - - - - - - - - - - - ABSTRACT The present invention relates to pickups for electrical musical instruments of the stringed type, having individual elements of unmagnetized material cooperating with the individual strings and separate magnets providing magnetizing force for the elements. Previous pickups of this type have employed magnet arrangements which provide relatively weak magnetic fields, resulting in an electrical output which is deficient to harmonics. No solution to the problem of harmonic deficiency due to weak magnetization has been known heretofore. The present invention overcomes this problem by use of a new magnet design and arrangement. A pickup is provided including a plurality of metallic, unmagnetized pole pieces having coil means wound around each piece and operatively associated with the strings of the instrument, the pole pieces being aligned in parallel, spaced- apart relationship, generally perpendicular to the plane of the strings, first ends of all of the pole pieces being closely adjacent to the strings, second ends of all of the pole pieces being flat and planar. The pickup further includes a rectangular bar magnet having a first surface defining a north pole and an opposite second surface defining a south pole, the bar magnet of the pickup being positioned with one surface which defined a pole thereof in surface contact with the second ends of all of the pole pieces. In a humbucking embodiment, the pickup includes a second set of magnets, pole pieces and coils.
