A musical instrument pickup, relating to a stringed instrument having at least one string, the at least one string having a longitudinal axis, comprising:
- a) a plurality of independent coil-wire wrappings, each having a geometric cross-section, able to be arranged together in an interlocking fashion;
- b) a plurality of pole pieces, each having a center and a longitudinal axis orthogonal to the longitudinal axis of each string;
- c) wherein the center of each pole piece of said plurality of pole pieces is arranged along a line having a constant angle with respect to the longitudinal axis of the at least one string;
- d) wherein at least one coil-wire wrapping of said plurality of coil-wire wrappings surrounds at least one pole piece of said plurality of pole pieces, wherein the wrapping direction of coil wire of said at least one coil-wire wrapping is substantially orthogonal to the longitudinal axis of the pole pieces;
- and
- e) wherein, when said plurality of coil-wire wrappings are arranged in an interlocking fashion,
- i) a first plane, passing through a mid-point between adjacent pole pieces, such first plane being parallel to the longitudinal axis of the pole pieces and perpendicular to such line having a constant angle with respect to the longitudinal axis of the at least one string, intersects each coil-wire wrapping of adjacent coil-wire wrappings;
- and
- ii) a second plane, passing through the longitudinal axis of a pole piece, such second plane being perpendicular to such line having a constant angle with respect to the longitudinal axis of the at least one string, intersects only one coil wire wrapping.

A method of constructing a musical instrument pickup, relating to achieving a user-desired signal output level and a user-desired tonal characteristic from a stringed instrument having at least one string having a longitudinal axis, comprising the steps of:
- a) selecting at least one geometric cross-section to embody a plurality of independent coil-wire wrappings, each independent coil-wire wrapping of such plurality able to be arranged together in an interlocking fashion, and further, such independent coil-wire wrappings being structured and arranged to surround at least one magnetic pole piece having a center and a longitudinal axis orthogonal to the longitudinal axis of the at least one string;
- b) wherein the step of selecting said at least one geometric cross-section comprises the step of selecting at least one coil angle, the coil angle defined by the angle formed by a longitudinally extending line oriented skew with respect to the longitudinal axis of the at least one string;
- c) selecting at least one coil-wire gauge for each independent coil-wire wrapping;
- d) selecting a number of winding turns of such selected coil-wire gauge for each independent coil-wire wrapping;
- and
- e) assembling, for use with the stringed instrument, a plurality of independent coil-wire wrappings having such selected geometric cross-section, such selected coil angle, such selected coil-wire gauge, and such selected number of winding turns such that, when such plurality of independent coil-wire wrappings are assembled in such interlocking fashion, and when the centers of each magnetic pole piece are arranged along a line having a constant angle with respect to the longitudinal axis of the at least one string, the musical instrument pickup is defined by
- i) a first plane, passing through a mid-point between adjacent magnetic pole pieces, such first plane being parallel to the longitudinal axis of the magnetic pole pieces and perpendicular to such line having a constant angle with respect to the longitudinal axis of the at least one string, which intersects each coil-wire winding of adjacent coil-wire wrappings;
- and
- ii) a second plane, passing through the longitudinal axis of a magnetic pole piece, such second plane being perpendicular to such line having a constant angle with respect to the longitudinal axis of the at least one string, which intersects only one coil wire wrapping.
