The difference is instantly recognizable. AlumiCrown bridges increase sustain and tonal color from the moment you hit the first chord. You'll hear each string ring clearly. Saddled up with GraphTech String Savers, the AlumiCrown is lightweight and easy-to-install. Each bridge is precision-engineered and finished by hand, then anodized in a buttery, satin finish for great hand feel. Available in 11 colors.
