For the top bracing pattern, we use Scalloped X bracing for  “Luthier Made”  models, Scalloped XX Bracing for “Hand Made” models and Classical Lattise Bracing for the new SJ-171 model. In addition, we curved out both sides of the X bracings and one side of the XX bracings to help distribute the vibration of the strings from the bridge to the top more evenly, and produce rich sounds which sustain high to low notes.  Also, both models employ “X Bracing” to the back.  “X bracing” the back will allow it to vibrate like the top and create a richer, more rounded sound.
