Abstract
An acoustic instrument is provided with a torsion brace which contacts the upper and lower plates in only three locations. The first location is at the head of the body, the second is at the heel of the body, and the third is where the bridge connects to the upper plate. This arrangement provides structural support to the guitar body because it braces the head and heel of the body and also supports the upper plate where the bridge is attached. However, because the brace contacts the plates at its neck and heel and at the bridge the plates may vibrate freely. This structure has been shown to resist feedback, yet does not dampen the vibration of the plates. As a result, the sound, projection, and sustain of the guitar are not adversely affected.
