A pair of struts are connected to the arms of each cross brace adjacent the sound hole in the face of the guitar. Each strut has one end connected to the arm of one of the cross braces adjacent the sound hole. Each strut extends toward the head of the body in a direction from the face toward the back. The other end of each strut is disclosed in one embodiment as connected to a vertical brace secured to the rim of the guitar.

In a further embodiment, the lowermost end of each strut is connected to a transverse brace which is secured to the internal surface of the back of the guitar. In a still further embodiment, the struts are adjustable so that their length and position of securement on the cross brace or other parts of the body of the guitar can be varied.
