Design of electric guitar 8 strings with combination of smartphone devices as a virtual guitar effect using reverse engineering method

Electric guitar is an instrumental instrument that is widely used in music, because with an electric guitar the music played will be more varied. That happens because of the supporting devices, namely the effect of the pedals that are used as setting the sound variations of the electric guitar being played. With the development of smartphone devices and applications on the Android and IOS platforms, the application developers made a new breakthrough by creating a virtual application of guitar effects that could be used like a pedal effect with sound results not much different from the original. then, electric guitars for now, still rely on the number of 6 strings, but some guitarists cannot reach out to the music genre that requires low and heavy tones, therefore, it is necessary to add 1 or 2 strings in order to get a low tunning sound character and increasing the number of frets on the fretboard to 30 frets, the more new tones that can be explored. Then, carried out with a reverse engineering method approach, to combine a smartphone device as a virtual effect on an electric guitar that can include several existing guitar concepts into an electric guitar unit that will be able to answer the wishes of progressive guitarists. And it was concluded that the electric guitar made meets the criteria such as low-tunning sound character, articulation and playbility aspects. then, the electric guitar manufacturing process was carried out by Luther Wira Musica, a home industry scale.
