Abstract
A humbucker pickup for creating electrical signals indicative of the string vibrations of an electric guitar includes a matched pair of elongated coil assemblies and a transversely polarized permanent magnet disposed between and parallel to the coils. Each coil assembly includes a flat vertically oriented core plate which is reduced to partial height in one portion of its length. The core structures are disposed parallel to each other but with the partial height portions of the core plates at opposite ends of the respective core structures. Under each string of the instrument the full-height portion of one core plate forms a tall pole piece adjacent the string for concentrating the magnetic field through the string, while the reduced-height portion of the other core plate forms a short pole piece spaced away from the string.
