摘要: The present invention is a bridge truss that alleviates tensile and compressive stresses applied to an acoustic stringed instruments soundboard from the bridge. These are transferred through chamber of instrument instead. allows support brace be reduced or eliminated. provides with ability produce longer sustained vibrations, vibrations greater amplitude—increasing performance tone. Also, relative height can altered for playability, at user's discretion. A user only needs reposition threaded adjustment rods atop in order transfer more less stress truss.
