Passive electromagnetic string isolating pickup
First Claim
1. An apparatus for a passive electromagnetic pickup for an electronic instrument having metal strings, the apparatus comprising:
- a first circuit comprising a first coil arranged in series with a second coil;
wherein the first circuit is configured to isolate at least two strings of the electronic instrument; and
a second circuit comprising a third coil arranged in series with a fourth coil;
wherein the second circuit is configured to isolate at least two other strings of the electronic instrument, wherein each of the coils of the first circuit and the second circuit comprise thousands of wraps of wire wound on a bobbin, wherein the bobbins of the first circuit and the bobbins of the second circuit comprise a different number of wraps, wherein a number of wraps for each bobbin of the first circuit is determined from a number of coils that are included within each circuit of the apparatus, wherein a number of wraps for each bobbin of the second circuit is determined from the number of coils that are included within each circuit of the apparatus.

Abstract
A passive pickup that utilizes electromagnetic coils comprising circuits that are connected in series and placed underneath and parallel to the strings of the electrical instrument. Each circuit within the passive pickup can be run through separate amplifiers in stereo or combined with standard guitar pickup signals and run through one or more amplifiers. The passive string isolating pickup is directed at allowing utilization of signal processing (guitar effects) in a string-isolated mono or stereo manner and the adjustment the volume and tone of isolated strings when wired in conjunction with volume and tone potentiometers.
