ABSTRACT:
The nut of a guitar includes several separate string-clamping blocks forming a row extending laterally of the guitar strings with each string being fitted between adjacent blocks. A bolt extending through the blocks has an enlarged head engaging the block at one end of the row and is threaded into the block at the other end of the row. Turning of the bolt in one sense tends to move the end blocks toward each other, thereby clamping the strings between the blocks and preventing movement of the strings across the nut as the guitar is played. The bridge of the guitar includes a movable bridge mounting plate which can be manipulated so as to produce a tremulous tone effect. The low friction pivot mounting for the bridge mounting plate consists of a sharpened end of the plate received in a transverse groove of a mounting flange. Alternatively the bridge mounting plate can be locked in fixed position relative to the remainder of the guitar body. The guitar strings are anchored closely adjacent to the bridge mounting plate and closely adjacent to the points where they cross the bridge to reduce the possibility that they will slide across the bridge as the guitar is played.
