Abstract
An electromagnetic pickup for electric guitars has one or two dual-coil assemblies wherein an inner coil is wound around a bobbin and then an outer coil around the inner coil. In the dual-coil assembly the inner coil replaces the entire or part of wall space of pole piece holes in a plastic molded bobbin. The outer and inner coils in the dual-coil assembly are electrically connected in-phase to produce single coil pickup sound. The outer coil or the serially connected inner and outer coils are connected to a coil in the other pole piece/bobbin/coil assembly out-of-phase to generate humbucking pickup sound.
