Abstract
Abstract A guitar bridge including a main body having adjustable support plates over which the guitar strings pass under tension. The main body of the guitar bridge is secured to an installation block which is, in turn, secured to the body of the guitar. The securement of the main body of the guitar bridge to the installation block is by way of an installation screw which is screwed into the support stand inside the body of the guitar. The upper end of the installation screw is domed and the receiving opening for the installation screw in the main body of the guitar bridge is correspondingly domed. A screw threaded extension up from the domed end of the installation screw is received by a tightening nut near the top of the guitar bridge and tightening of that nut on the extension of the installation screw tightens the installation screw into the domed opening in the guitar bridge main body.
