Abstract: This invention continues and adds to the embodiments under Non-provisional patent application Ser. No. 16/840,644, adding circuits using small dual-coil humbucking pickups made to mount in the same holes as and replace single-coil pickups. It also develops circuits to match the value of tone capacitors to the lumped inductances of pickup circuits. A mechanical switching system for 3 single-sized humbuckers can produce 21 distinct tonal circuits from 48 different switch combinations, using a 6-way circuit switch and three 2-way mode switches. A digitally-controlled solid-state switching system can avoid the duplicate circuits, and control even more pickups for more tones.

Abstract: A modular single-coil electromagnetic stringed-instrument pickup, made to mount in replacement of a standard single-coil pickup, using the similar mounting screws and springs, has a replaceable base, core, blade pole and cover. The core unit has two flat coil forms glued to a bar magnet, which together form a trough for the coil. The outsides of the coil forms have printed circuits which form the coil end contacts and an integral electrostatic shield, with interconnect fixed after the coil is wound, so that the core unit can be flipped to change the magnetic polarity of the pickup, and thus the string vibration signal, while maintaining a humbucking pair circuit with equivalent pickup. The base, which can be either non-magnetic or ferro-magnetic material in different shapes and configurations to shape the magnetic field, contains three conductive index pins, which both make contact with the core unit contacts, and transmit string signals to any circuit or electrical contacts on the bottom of the base.
