This set is solid brass with a classy one-material finish.
John Pearse KingPins 6-pin bridge pin set for acoustic guitars. Made from bell-brass, the same brittle-bronze material used in the manufacture of bells for its high-density and ability to store energy, JP KingPins eliminate much of the energy lost by standard plastic pins resulting in superior sustain and tone. If you’re struggling with weak bass or treble response then replacing your pins with brass KingPins can make all the difference.
Diameter (under the collar): 5.6mm
