Noise sensing bobbin-coil assembly for amplified stringed musical instrument pickups

A stringed musical instrument pickup comprising:

• at least one string-sensing coil, and
• at least one noise-sensing coil electrically coupled to the string sensing coil, the noise-sensing coil comprising a core, the core comprising steel laminations, whereby eddy current losses are reduced when a voltage is induced in the noise-sensing coil in order to cancel a noise voltage induced in the string-sensing coil;
• wherein the noise-sensing coil further comprises:
• at least one end plate extending transversely of at least one end of the core;
• and a coil of copper wire wound on the core, the at least one end plate comprises two end plates extending transversely of opposite ends of the core;
• wherein the steel laminations are H-shaped, the bridges of each H forming the core and the legs of the H forming the two endplates.
