An improved reverse tremolo bridge including a base plate attached to a guitar body, a camshaft connected to a slide plate, and cam stops connected to the base plate. Strings for the guitar are engaged to respective string saddles and pass through respective slots in the base plate and slide plate to a spring block. The string saddles are connected to the slide plate. The tension of the strings draws the slide plate toward the head of the guitar and hence brings the camshaft into contact with the cam stops. A handle is used to rotate the camshaft. The camshaft surfaces in contact with the cam stops are formed so that the longitudinal axis of the camshaft moves closer or further from the head of the guitar as the camshaft rotates. The slide plate moves with the camshaft, thereby decreasing or increasing, respectively, the tension on the strings.
