Abstract

A pickup for a guitar that has four (4) or more separate magnetic coils and selection means to select among the coil outputs. In some embodiments, the pickup is passive, not requiring an active pre-amplifier and voltage supply to shape the sound. In some embodiments, the selection means may be incremental or continuous, providing a wider degree to selectivity between and among the outputs of the separate coils.

Claims

1. A pickup device for a guitar comprising four or more magnetic coils, with a first two such magnetic coils having a first polarity positioned beside a second two other such magnetic coils having a second polarity, each magnetic coil configured to produce electrical signals when placed in proximity of a vibrating guitar string, connected on one end by a combination of at least one AlNiCo 5 magnet sandwiched between at least two ceramic magnets matching north magnetic poles to south magnetic poles so that the polarity of said first two such magnetic coils is opposite the polarity of said second two such magnetic coils, and a selection means to incrementally select among said electrical signals produced by one or more of the four or more magnetic coils.

2. The pickup device of claim 1 wherein, the selection means is configured to rotate smoothly and continuously to allow for smooth continuous adjustment through a spectrum of magnetic coil configurations from one magnetic coil to all magnetic coils for providing a wide degree to selectivity between and among electrical signals produced by the magnetic coils.

3. The pickup device of claim 1 wherein, the magnetic coils are configured to operate passively and not require an active pre-amplifier and voltage supply to produce said electrical signals.

4. A pickup device for a guitar comprising four or more magnetic coils, with a first two such magnetic coils positioned beside a second two other such magnetic coils, each configured to produce electrical signals when placed in proximity of a vibrating guitar string and having at least 8000 winds each to provide sufficient resistance without the aid of a separate power source, and a selection means to incrementally select among said electrical signals produced by one or more of the four or more magnetic coils.

5. The pickup device of claim 4 wherein, the selection means is configured to rotate smoothly and continuously to allow for smooth continuous adjustment through a spectrum of magnetic coil configurations from one magnetic coil to all magnetic coils for providing a wide degree to selectivity between and among the electrical signals produced by the magnetic coils.

6. The pickup device of claim 4 wherein, the magnetic coils are configured operate passively and not to require an active pre-amplifier and voltage supply to produce said electrical signals.
