Trussrods & reinforcing plates
The neck itself should be stiff, and transfer most of the vibration to the body of the guitar. The neck should not vibrate, or flex in balance between the string tension and a tightened truss rod. Vintage Maccaferri guitars even had their necks reinforced with aluminium plates.
All AJL guitars come equipped with a two-way adjustable truss rod, and can be ordered with additional carbon fiber reinforcment strips. These carbon fiber reinforced necks are even lighter, and stiffer. This enhancement causes the neck to be more stable, produces greater volume, and requires less seasonal adjustment.
