  • Patent number: 4320685
    Abstract: A guitar having a split level top of its sound box which thus is formed at two different (vertically separated) levels and connected by an angular cross bridge to which one end of the strings is anchored so as to directly vibrate the chamber. The result is an increased sound volume and resonance persistance which is achieved without the distortion that may result from electronic amplification when applied to conventional guitars or other stringed musical instruments.
