Gibson '57 Classic Plus, Alnico II Humbucker -Zebra. The perfect bridge-position companion to the '57 Classic, the '57 Classic Plus mimics those late-1950s humbuckers that received a few extra turns of wire. This treatment gave the pickup slighter higher output without sacrificing its rich, vintage tone. It helps overdrive tube preamps to a smooth level of saturation without becoming overpowering. Made with the same features as the '57 Classic, the '57 Classic Plus is available with genuine gold-plated covers, nickel-plated covers, or open coils.
