Carbon fiber rods provide strength and reinforcement to a guitar's neck. They can help prevent a super thin neck from flexing, correct warping issues and straighten a long bass neck to reduce the chance of breaking your truss rod.
Carbon Fiber rod installations will require removal of the fretboard. A refret or replacement of fretboard may also be necessary in some cases.
Remove (and replace) fretboard $160
Supply and fit carbon fiber rods $250
(Refret may apply)
