## Background
BACKGROUND
Technical Field
The embodiments herein are generally related to musical instruments. The embodiments herein are particularly related to electric guitars. The embodiments herein are more particularly related a system and method for instantly switching sound pickups in an electric guitar using a spin wheel arrangement while playing the electric guitar. The embodiments herein are also related to a system and method for providing a spin wheel arrangement in an electric guitar to allow a guitar player to add favorite pickups for generating a plurality of tones beyond a limit of a single guitar.
Description of the Related Art
Electric guitars are popular musical instruments capable of producing a wide range of sounds using an amplification device. A traditionally built electric guitar comprises one or more permanently installed pickups which are positioned beneath the metal strings. In general, the pickups are situated between an end of the neck's finger board and a bridge of the guitar. Each pickup is typically composed of a single coil having two wires connectable to a guitar output circuit. The output circuit is connected to an audio amplifier through a shielded two conductor cable.
The pickups captures a sound of a vibrating metal string and converts the mechanical vibrations to electrical signals. Magnetic pickups consists of a permanent magnet with a core made up of a material such as alnico or ceramic wrapped with a coil of several thousand turns of finely enameled copper wire. A disturbance in the magnetic field, produced by the vibrating string causes the coil of wire wound around the magnet to become a conductor for a flow of current. The current flow creates an electrical signal that is transmitted to a loudspeaker system after amplification.
Electric guitars normally have either one coil or a double coil arranged on the sound pick-up. The double coil has two electrically separated coils. The double coil is also known as a ‘humbucker pickup’. The best known pickup arrangements in the electric guitars are Gibson tonality and Fender tonality. The Gibson tonality comprises two sound pickups with a double coil whereas the Fender tonality comprises three sound pickups, each having one coil. The guitars with humbucker pickups are mostly used for producing hard rock sound or (fat sound). On the other hand, the Fender telecasters or Stratocasters are preferred for producing country sounds or twang.
Historically, many musicians desire to play the guitars that generate tonalities beyond the limit of a single guitar. For example, while playing a guitar with single coil pickups, musicians want to change the sound to another pick-up like a hum bucker, or p-90 or a Minnie hum bucker. Some of the existing systems allows the musicians to do hardware modifications of a specific component to achieve different tonality in same instrument. A single coil sound is achieved from a humbucker pickup by connecting one of the coils in the humbucker to ground. In this case, even though a single coil sound is produced, the humbucker does not produce a standalone single coil sound. Moreover, these systems limit a capability of a musician to dynamically alter the tonal characteristics. In some other existing systems, active electronics, new and different knobs or buttons, and switches are used to produce entirely new tones. But, such systems are hard-to-use and needs additional care while using the guitar.
Hence, there is a need for a system and method for instantly switching sound pickups in an electric guitar using a simple spin wheel arrangement while playing the electric guitar. Further, there is a need for a system and method for providing a spin wheel arrangement in an electric guitar that allows a guitar player to add favorite pickups for generating a plurality of tonalities beyond the limit of a single guitar. There is also a need for a system and method for easily rolling a neck pickup of the electric guitar to a bridge position and bridge pickup of the electric guitar to a neck position instantly in the middle of a song.
The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.

The copper plungers of the corresponding pickups under the guitar strings make contact with contact pads of the guitar body (1003). The contact pads mate/engage with the copper plungers and establish electrical connections between the pickups and the electronic control components of the guitar. After establishing the electrical connection, the pickups under the guitar strings get activated and the pickups away from the guitar strings are completely off (1004). Thus, the spin wheel arrangement allows a guitar player to switch the pickups in the electric guitar instantly by rotating the spin wheel in the middle of a song.
The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the appended claims.
Although the embodiments herein are described with various specific embodiments, it will be obvious for a person skilled in the art to practice the invention with modifications. However, all such modifications are deemed to be within the scope of the claims.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the embodiments described herein and all the statements of the scope of the embodiments which as a matter of language might be said to fall there between.

## Claims

1. An electric guitar, said electric guitar comprising:
a guitar body, said guitar body comprising a circular groove for receiving a center-screw;
a spin wheel assembly, said spin wheel assembly rotatably mounted on the guitar body using the center-screw, said spin wheel assembly configured to be selectively rotated in a clock-wise direction and counter clock-wise direction while said electric guitar is being played, said spin wheel assembly comprising:
at least two pickups arranged on a horizontal axis thereof, and at least two pickups arranged on a vertical axis thereof; and

said spin wheel assembly further configured to be selectively rotated across the guitar body while said electric guitar is being played, thereby activating either of the pickup heads located on the horizontal axis and the vertical axis, based on degree of rotation and direction of rotation thereof, said spin wheel assembly further configured to be rotated in a semi-circular manner across the guitar body, while said electric guitar is being played, to switch between said two pickups arranged on said horizontal axis and said two pickups arranged on said vertical axis, and wherein each of said pickups are connected to corresponding spring-loaded plungers via respective hot wires, said spring-loaded plungers operatively coupled to a plurality of contact pads thereby establishing an electrical connection between each of the pickups and electronic control components of the electric guitar.

2. The electric guitar as claimed in claim 1, wherein said spin wheel assembly further comprises a spin wheel, said spin wheel constructed as a combination of a top plate and a bottom plate held together by a plurality of screws, said pickups arranged on the horizontal axis and vertical axis of the top plate, said bottom plate incorporating said spring-loaded plungers.

3. The electric guitar as claimed in claim 1, wherein said circular groove forms a center stub on the guitar body, said center stub configured to receive the center-screw, and wherein said center stub provides an axis of rotation for the spin wheel assembly in the clock-wise direction and counter clock-wise direction.
