Abstract

A parallel tapped magnetic pickup for an electrical stringed musical instrument is provided. The parallel tapped magnetic pickup comprises a coil formed with at least two parallel connected wound wires. A guitar in combination with the parallel tapped pickup is additionally provided.

Claims

1. A pickup for a stringed electrical musical instrument comprising:

a permanent magnet; and

a coil associated with the magnet, wherein the coil is wound separately with at least two wires, further wherein a second wire of the at least two wires is connected with a first wire in a parallel connection.

2. The pickup of claim 1 wherein the first wire has a first end connected with a ground and a second end connected with an output.

3. The pickup of claim 2 wherein the second wire has a first end connected with the output.

4. The pickup of claim 3 wherein the second wire has a second end connected with a switch.

5. The pickup of claim 1 further comprising:

at least one pole piece associated with the magnet, wherein the coil is placed around the at least one pole piece.

6. The pickup of claim 5, further comprising:

a bobbin, wherein the bobbin is placed around the at least one pole piece, further wherein the coil is wound around the bobbin.

7. The pickup of claim 6 wherein the bobbin is a generally rectangular shape.

8. The pickup of claim 1 wherein the permanent magnet is an Alnico magnet.

9. The pickup of claim 1 wherein the permanent magnet is a ceramic magnet.

10. The pickup of claim 1 wherein the at least two wires are wound about 4000 times.

11. The pickup of claim 1 wherein the at least two wires are insulated copper AWC 42.

12. A stringed electrical musical instrument comprising:

a guitar;

a pickup mounted on the guitar, wherein the pickup comprises a permanent magnet; and

a coil associated with the magnet, wherein the coil is wound with at least two wires, further

wherein a second wire of the at least two wires is connected with a first wire in a parallel connection.

13. The pickup of claim 12 wherein the first wire has a first end connected with a ground and a second end connected with an output.

14. The pickup of claim 13 wherein the second wire has a first end connected with the output.

15. The pickup of claim 13 wherein the second wire has a second end connected with a ground.

16. The stringed electrical musical instrument of claim 13 further comprising:

at least one pole piece associated with the magnet, wherein the coil is placed around the at least one pole piece.

17. The stringed electrical musical instrument of claim 16, further comprising:

a bobbin, wherein the bobbin is placed around the at least one pole piece, further wherein the coil is wound around the bobbin.

18. The stringed electrical musical instrument of claim 17 wherein the bobbin is a generally rectangular shape.

19. The stringed electrical musical instrument of claim 13 wherein the permanent magnet is an Alnico magnet.

20. A stringed electrical musical instrument comprising:

a guitar; and

a pickup mounted on the guitar, wherein the pickup comprises a permanent magnet, wherein the permanent magnet is an Alnico magnet;

a coil associated with the magnet, wherein the coil sections are wound separately with at least two wires, further wherein the at least two wires are wound in a tapped parallel manner, wherein the first wire has a first end connected with a ground and a second end connected with an output, further wherein the second wire has a first end connected with the output and a second end connected to a switch;

at least one pole piece associated with the magnet, wherein the coil is placed around the at least one pole piece; and

a bobbin, wherein the bobbin is placed around the at least one pole piece, further wherein the coil is wound around the bobbin, wherein the bobbin is a generally rectangular shape.
