Abstract: Magnetic pickup systems suitable for use with stringed instruments and methods for their use. Such a pickup system includes a wire coil that has an axis and is wound onto a core of a coil bobbin, and magnetic strips outside the wire coil. The magnetic strips each have a polarization axis orthogonal to the axis of the wire coil. A longitudinal center of the coil bobbin is populated with core elements having high gauss permanent magnets attached thereto. The high gauss permanent magnets each have an axis of polarization disposed parallel to the axis of the wire coil and therefore in an orthogonal orientation to the polarization axes of the outboard magnetic strips. A method of using such a pickup system includes adjusting one or more of the core elements relative to the outboard magnetic strips to allow for selectively and individually increasing a range of flux field geometries of one or more strings of the stringed instrument.

Abstract: Electromagnetic transducers suitable for a variety of uses, including but not limited to musical instrument pickups. Such a transducer has a primary loop formed by an electrically conductive strip having oppositely-disposed ends and a slot extending therebetween that defines electrically conductive runners. The strip is bent to define a first section of the primary loop that overlies a second section of the primary loop and a gap therebetween. The transducer further comprises sensing or driving elements that are at least partially received in the slot in the first section of the primary loop and a transformer electrically connected to the strip at one of the ends thereof opposite the first section of the primary loop.
