Abstract: An improved hum-cancelling pickup (humbucker) comprises a single integrated coil. The device includes a bobbin having a top plate and a bottom plate interconnected by a plurality of magnetic pole pieces and a fine enameled wire wound around the magnetic pole pieces a plurality of turns so as to form a coil; the coil having dual inner and outer wrappings each wound around the magnetic pole pieces in a direction reverse of the other wrapping. The inner and outer wrappings of the coil are coupled to a single magnetic field that can be positioned at a single location along the strings of a musical instrument, allowing for improved fidelity of string signals while cancelling signals induced in the coil by ambient magnetic fields.
