Subfretboard is a piece of metal strategically designed to improve the quality of sound in any plucked string instrument. Therefore, we have developed a neck thru prototype whose sound characteristics are as natural and inherent to the instrument as absolutely satisfying, resulting in unique quality benefits in his genre and being within the field of physics and not as an electrical invention.With this system the sound has improved remarkably in balance between strings, increasing the output of harmonics, volume and natural sustain. These benefits are obtained with a piece of metal inserted into the guitar and in turn a new type of construction is required, being able to apply over any other traditional kind of construction.We are available to negotiate the purchase of legal licenses for the use of our system in the construction of any plucked string instrument to obtain a significant improvement of sound.In terms of the patent we have the International Search Report (ISR) and Report on the State of the Art (RSA) with 100% propitious evaluation
