      at the neck block through the sound hole, shows access hole through the
                                        neck block for truss rod adjustment. All CB guitars feature an adjustment nut
      that is accessible through the end of the neck block by simply reaching
      inside the guitar behind the transverse brace underneath the end of the
                                        fretboard. This allows for
      easily-accessible neck adjustment while maintaining the structural
      integrity of the guitar by not drilling the transverse brace for truss rod
                                        access as some manufacturers do, which
                                        weakens the top at this critical stress

                                              block to receive the neck
                                              dovetail. Great care must be taken
                                              to insure that the neck dovetail
                                              exactly fits this body dovetail,
                                              and that the neck angle is set
                                              correctly, as there is no margin
                                              for error here. Also shown is the
