ABSTRACT:
This invention is a multi-action device for controlled correction of bowing in the neck of a stringed musical instrument. It comprises a ridged metal bar main frame immediately under the fingerboard and running lengthwise and on centerline. Primary adjustment is made by applying pressure directly to the end of the main frame at the heel end of the neck. Secondary adjustment is made by applying pressure to an eyelet affixed on the bottom side of and on the heel end of the main frame. The adjusting nut for secondary adjustment is on the threaded end of an anchor rod that passes through the eyelet with the other end of the rod welded to a predetermined location on the underside of the main frame. An alternate to the anchor rod is an anchor stud mounted in the heel end of the neck and passing through the eyelet. Primary and secondary adjustments are the same as for when the rod is used. Further control can be exercised by pre-stressing, slotting, and/or establishing pressure points on end of the main frame.
