ABSTRACT:
A stringed instrument having a hollow body including a top wall, a spaced apart bottom wall, and a side wall interconnecting the top and bottom wall, each of the walls having a plurality of strategically located sound holes which efficiently release sound vibrations generated within the hollow body of the instrument. The stringed instrument also includes an extended bridge disposed internally of the hollow body and interconnecting the top and bottom walls in a manner to transmit vibrations formed in the top wall to the bottom wall thereby making two sound boards increasing vibration and in so doing increasing sound dynamics and volume of the instrument.
