String instrument formed as an integral unit structure

A stringed musical instrument, comprising:

• a unitary structure formed integrally by a body, a neck and a head;
• front panels that seal the body at the front, the front panels provided with connection means to connect the panel to said body;
• and
• rear panels that seal the body at the back, the rear panels provided with connection means to connect the panel to said body;
• wherein:
• the unitary structure is formed from a solid block of rigid non-wood material by computer numerical control (CNC) machining;
• the body includes a front part with a plurality of cavities and housings arranged at predetermined locations and intervals, at least some of said cavities and housings being communicated internally by openings arranged at the side walls thereof to form an interconnected network;
• a rear part with housings for the housing of the structure of a tail piece that is integrally comprised in said unitary structure and of a power source respectively;
• and open chambers that extend between said front part and said rear part and are delimited by at least some internal ribs;
• the neck comprises a side wall provided with fixing means for fixing a fingerboard, a bottom wall and a central rib;
• the stringed instrument further comprises a metal fingerboard with a compound-radius design machined by CNC from a solid block of rigid non-wood material as a single piece and connected to said unitary structure in a removable and interchangeable manner;
• said fingerboard comprising connection means arranged in the lateral walls of the same to connect the fingerboard to the neck such that the fingerboard is connected laterally;
• said connection means being complementary with the fixing means arranged on the neck;
• and
• the stringed instrument further comprises a bridge machined by CNC from a solid block of non-wood rigid material and mounted on the front part of the body.
