Humbucker pickup device for active and passive guitars

In a humbucker pickup device for active and passive guitars including a matched pair of elongated coil assemblies placed closely in parallel, two sets of ferromagnetic pole pieces extending through said coil assemblies, one set for each coil, in which said pole pieces having the upper ends disposed adjacent ferrous strings of a guitar so that each string is over two respective pole pieces, one from each set, an improvement for the interaction of the magnetic field with a string at two points, comprising:

• two transversely polarized permanent magnets, each in the form of an elongated bar having a rectangular cross-section and opposed longitudinal surfaces constituting pole faces, north and south respectively, said north pole surface of one magnet and south pole surface of the other magnet facing each other, attracting said magnets closely back to back;
• said magnets disposed below both of said coils and between said two sets of pole pieces, wherein two other, outer pole surfaces of said magnets also with opposite poles engage to the lower ends of pole pieces of a first and a second sets respectively, inducing opposite poles on said two respective pole pieces under each string and thereby providing opposite magnetic polarities for said coils wounded in the same direction;
• said two respective pole pieces providing a wide intermediate magnetic field between them weakened near a string and two outer narrow more strong magnetic fields applied to said string, with said two magnets having the opposite north/south poles in the middle between said two respective pole pieces there is a decrease in intensity of said wide intermediate magnetic field near the string, thereby the string is more free in its vibrations providing an improved string signal picked up at two points by said narrow magnetic fields.
