Vintage details.
The look is right at home on vintage-style instruments. Authentic "Butterbean" knobs (a description coined by the late Martin historian Mike Longworth) are solid brass, not die-cast, with the historically-correct shape not found on other modern tuners.

• Set of 6: 3-left/3-right
• Mounting screws and bushings included

The sturdy steel baseplates have the authentic 1930s footprint. String posts are vintage-style tapered 1/4"-diameter brass, with press-fit knurled brass hex bushings to fit 11/32"-diameter pegholes. Slot-head mounting screws complete the vintage look; there are no additional holes to drill on many older Martins and Gibsons.
