For the elaboration of the soundboard of the 5 P model, which together with the top is what most influences the sound of the guitar, a bracing design has been used that consists of a thin wood that is supported by seven bars, two of them at the bottom. This construction detail contributes to achieving a more resistant instrument, but at the same time light, as well as improving the sound, giving it more body, warmth and richness. For the “bones”, both in the saddle and in the nut, melamine has been used, a highly transmitting material of sound. A sound that in this case could be described as more defined, melodious and with a constant tone throughout the neck. An example of this is the sound quality of the first three strings at fret number 12.
