Lo impedance dual coil bifilar magnetic pickup
View Patent ↗A bifilar pickup for an electrical stringed musical instrument is provided. The bifilar pickup comprises a dual coil wherein at least one coil is formed with two closely spaced bifilar parallel wound wires. A guitar in combination with the pickup unit is additionally provided.
1. A pickup for a stringed electrical musical instrument comprising: a humbucking pickup with at least two permanent magnets; and a coil associated with each magnet, wherein at least one coil is wound with at least two non-ferromagnetic copper wires, further wherein the at least two wires are wound in a parallel manner with coaxial turns, and yet further wherein the at least two wires are electrically connected to each other on at least one end but electrically isolated from each other in the coaxial turns.
2. The pickup of claim 1 , wherein the at least two permanent magnets are oppositely polarized permanent magnets.
3. The pickup of claim 2 wherein the two oppositely polarized permanent magnets are Alinco 5 magnets.
4. The pickup of claim 1 , wherein the at least two coils are electrically connected.
5. The pickup of claim 4 , wherein the at least two electrically connected coils are connected in phase parallel, in phase series, out of phase parallel, or out of phase series.
6. The pickup of claim 1 , further comprising two bobbins, wherein each bobbin is associated with one of the at least two magnets, further wherein at least one coil is wound around one of the two bobbins.
7. The pickup of claim 1 wherein the at least two wires are wound about 4000 times.
8. The pickup of claim 1 wherein the at least two wires are insulated copper AWC 44.
9. A stringed electrical musical instrument comprising: a guitar; and a humbucking pickup mounted on the guitar, wherein the pickup comprises at least two permanent magnets; and coil associated with each magnet, wherein at least one coil is wound with at least two non-ferromagnetic copper wires, further wherein the at least two wires are wound in a parallel manner with coaxial turns, and yet further wherein the at least two wires are electrically connected to each other on at least one end.
10. The stringed electrical musical instrument of claim 9 wherein the coils are electrically connected.
11. The stringed electrical musical instrument of claim 10 , wherein the electrically connected coils are connected in phase parallel, in phase series, out of phase parallel, or out of phase series.
12. The stringed electrical musical instrument of claim 9 , wherein the at least two permanent magnets are two oppositely polarized magnets.
13. The stringed electrical musical instrument of claim 9 wherein the coils are attached to a single base.
14. The stringed electrical musical instrument of claim 9 wherein the at least two wires are wound about 4000 times.
15. The stringed electrical musical instrument of claim 9 wherein the at least two wires are insulated copper AWC 44.
