Abstract:
A guitar comprising:a body;a neck which is connected to the body and which extends away from the body, wherein the neck has portions which define a recess which extends along the axis of the body, wherein a fingerboard is positioned on the neck, and wherein the neck has a headstock end which is spaced from the body, and a body end which is connected to the body;a plurality of strings which are fixed to the neck and which extend to the body and are fixed to the body, the strings exerting a tension force between the neck and the body;a U-shaped channel member which is positioned in the neck recess and has a headstock end and a body end, the channel member having a floor which is positioned beneath the fingerboard;a rod which extends through the channel member from the body end to the headstock end, wherein the rod has threaded portions which protrude beyond the channel member body end, the rod having a body end which engages with the channel member floor, and the rod having a headstock end which engages with the channel member floor;an adjustment nut threaded on the rod threaded portion and engaged with the channel member body end, such that the adjustment nut may be rotated to draw the adjustment nut and the channel member body end closer to the channel member headstock end, and thereby apply tension to the rod and compression to the channel member;a first spacer having portions extending between the rod and the channel member floor to space the rod from the channel member floor away from the fingerboard, the first spacer being positioned along the rod between the headstock end of the channel member and the body end of the channel member, the rod being thereby caused to bow away from the floor of the channel member; anda second spacer having portions extending between the rod and the channel member floor to space the rod from the channel member floor away from the fingerboard, the second spacer being positioned along the rod between the first spacer and the headstock end of the channel member, wherein a first region is defined between the body end of the channel member and the first spacer, a second region is defined between the first spacer and the second spacer, and a third region is defined between the second spacer and the headstock end of the channel member, and wherein the adjustment nut may be rotated to cause the channel member to counteract the distortion of the neck caused by the string tension.
