• A classy vintage aesthetic enhanced for modern performance.

Optional light-weight carbon fiber plate (Gotoh C.A.R.D system) is included, but is not necessary for installation of the Tuners.  C.A.R.D. system adds the following benefits:

• Carbon Fiber Plate helps transfer resonance from strings from tuner to headstock improving sustain and harmonics
• Plate design centers tuners and lines them up perfectly to ensure error free mounting
• Protects headstock from damage from metal edges of tuner. 

Note that in some cases the backside of the tuner holes may have to be reamed out to fit the C.A.R.D. plate.
