wherein the pickup is disposed between the removable neck and body portions of the musical instrument such that the pickup is exposed when the removable neck is disengaged from the body portion and such that the pickup is substantially hidden when the removable neck is engaged with the body portion.

2. The electromagnetic pickup of claim 1 , wherein each of the at least one pole piece is disposed substantially aligned with a respective musical instrument string.

3. The electromagnetic pickup of claim 2 , wherein the musical instrument further comprises a recessed area in a top surface of the body portion dimensioned to receive the pickup.

4. The electromagnetic pickup of claim 3 , wherein the recessed area includes an aperture dimensioned to receive each pole piece.

5. The electromagnetic pickup of claim 4 , wherein each aperture is substantially circular.

6. The electromagnetic pickup of claim 1 , wherein the neck portion includes an interior surface having a cut out dimensioned to receive a portion of the pickup.

7. The electromagnetic pickup of claim 1 , wherein:

the musical instrument includes 6 strings; and

the at least one pole piece includes 5 pole pieces, each pole piece disposed substantially aligned with a respective string.

8. The electromagnetic pickup of claim 7 , wherein the string that does not include an associated pole piece is a treble string.

9. The electromagnetic pickup of claim 1 , wherein the pickup further comprises lead wires for attachment to amplification equipment.

10. The electromagnetic pickup of claim 1 , wherein the pole pieces are substantially cylindrical.

11. The electromagnetic pickup of claim 1 , wherein the musical instrument is a guitar.

12. The electromagnetic pickup of claim 1 , further comprising a spacer disposed between the bobbin and one of the pole pieces.

13. The electromagnetic pickup of claim 1 , wherein the at least one pole piece comprises a single elongate pole piece disposed substantially aligned with two or more of the strings.

14. The electromagnetic pickup of claim 13 , wherein the musical instrument further comprises a recessed area in a top surface of the body portion dimensioned to receive the pickup.

15. The electromagnetic pickup of claim 14 , wherein the recessed area includes an aperture dimensioned to receive the single elongate pole piece.

16. A stringed musical instrument including an electromagnetic pickup, comprising:

a body portion including a recessed area shaped and sized to receive the pickup; and

a neck portion removably attached to the body portion such that the pickup is sandwiched between the removable neck and body portions;

wherein the pickup includes a bobbin, a coil wound around the bobbin, and at least one pole piece coupled to the bobbin,

wherein the bobbin is configured to be adjacent strings of the musical instrument and the bobbin defines a volume that is void of magnetic material, and

wherein the pickup is substantially invisible to a user of the musical instrument.

17. An electromagnetic pickup comprising:

a non-magnetic bobbin having a top surface and a bottom surface, the bobbin being configured to be disposed adjacent strings of a stringed instrument;

a coil wound around the bobbin; and

at least one pole piece fixedly coupled to the bottom surface of the bobbin,

wherein the bobbin defines a volume that is void of magnetic material.

18. The electromagnetic pickup of claim 17 , further comprising a non-magnetic spacer disposed between the bobbin and the at least one pole piece, wherein the at least one pole piece is fixedly coupled to a bottom surface of the bobbin such that the spacer is interposed between the at least one pole piece and the bottom surface.
