Abstract

According to some embodiments, a musical instrument pickup comprises a first plurality of non-magnetic pole pieces a second plurality of non-magnetic pole pieces, a plurality of magnetic pole pieces, a first coil disposed around the first plurality of non-magnetic pole pieces, a second coil disposed around the second plurality of non-magnetic pole pieces and the plurality of magnetic pole pieces, and a bar magnet magnetically coupled to the first plurality of non-magnetic pole pieces and the second plurality of non-magnetic pole pieces.

Claims

1. A musical instrument pickup, comprising:

a first plurality of non-magnetic pole pieces;

a second plurality of non-magnetic pole pieces;

a plurality of magnetic pole pieces;

a first coil disposed around the first plurality of non-magnetic pole pieces;

a second coil disposed around the second plurality of non-magnetic pole pieces and the plurality of magnetic pole pieces; and

a bar magnet magnetically coupled to the first plurality of non-magnetic pole pieces and the second plurality of non-magnetic pole pieces, wherein the plurality of magnetic pole pieces are not magnetically coupled to the bar magnet.

2. The musical instrument pickup of claim 1, further comprising:

a plurality of non-conductive pole pieces.

3. The musical instrument pickup of claim 1, wherein the plurality of magnetic pole pieces comprise alnico magnets.

4. The musical instrument pickup of claim 1, wherein the first plurality of non-magnetic pole pieces comprise screws.

7. The musical instrument pickup of claim 1, wherein the second plurality of non-magnetic pole pieces and the plurality of magnetic pole pieces comprise an equal number of pole pieces.

8. The musical instrument pickup of claim 1, wherein the second plurality of non-magnetic pole pieces and the plurality of magnetic pole pieces are cylindrical shaped.

9. The musical instrument pickup of claim 1, wherein the bar magnet is disposed beneath the first coil and the second coil.

10. The musical instrument pickup of claim 1, further comprising:

a base plate, wherein one or more of the plurality of magnetic pole pieces extends through the base plate.

11. A musical instrument pickup comprising:

one or more first non-magnetic pole pieces;

one or more second non-magnetic pole pieces;

one or more magnetic pole pieces;

a first coil disposed around the one or more first non-magnetic pole pieces;
