Abstract

An electromagnetic pickup for electric guitars has a plural of wire coils around each pole set and two lead wires connected to each wire coil. Individual wire coils around a pole set have different oxygen contents and/or gages and/or turns and/or coating materials such that one wire coil produces a tone color distinctive from another wire coil.

Claims

1. An electromagnetic pickup with humbucking configuration (the said HB pickup) wherein two pole set/bobbin and wire assemblies are situated side by side and one wire from one pole set/bobbin assembly is electrically connected to one wire from the other assembly such that two wires are electrically in-phase or out-of-phase, and wherein at least one of the two pole set/bobbin assemblies contains a plural of wire coils with different specifications in terms of oxygen contents and/or gages and/or turns and/or coating materials.

3. An electromagnetic pickup with the humbucking configuration as claimed in claims 1 and 2, wherein the pole pieces are either magnetic or non-magnetic.

2. An electromagnetic pickup with the humbucking configuration wherein two pole set/bobbin and wire assemblies are situated side by side and one wire from one pole set/bobbin assembly is electrically connected to one wire from the other assembly such that two wires are electrically in-phase or out-of-phase, wherein at each side of pole set/bobbin and wire assembly, a plural of bobbins are aligned, stacked, and assembled with pole pieces running through them, wherein each bobbin is wound with a wire coil with a certain specifications, and wherein a plural of bobbins in the same side are wound with wire coils with different specifications in terms of oxygen contents and/or gages and/or turns and/or coating materials.
