Abstract
A magnetic pickup for a stringed musical instrument has one or more composite ferromagnetic pole pieces. The composite pole pieces have two or more components with different ferromagnetic materials properties in fixed and contiguous positions. The tonal properties of the pickup are partially determined by the materials and arrangement of the components and are variable over a wide parameter space. Pickups with composite pole pieces and methods for reconfiguring pickup with monolithic pole pieces are described.
