Abstract: An Exchangeable Stacked Pickup Assembly for Stringed Instruments is disclosed. The preferred system and assembly permit the user to change magnet characteristics and/or the number of coil windings without necessitating string removal and subsequent guitar re-tuning. The pickup system further includes a lower coil assembly for attaching to the face of a guitar or other stringed instrument, and an upper coil assembly for attaching to, and detaching from the lower coil assembly. As described, the lower coil assembly and the upper coil assembly include conventional pickup coil assemblies, which are in electrical circuit when attached to one another. Furthermore, the preferred system includes a variety of upper coil assemblies, each having unique electromagnetic qualities, such that the user need only exchange one upper coil assembly with another in order to effect a desired change in sound to the stringed instrument.
