The EMG-JHZ BLACK Set uses a stacked design with ceramic magnets and a laminated steel core for increased output and lower noise. Included is one long (bridge) pickup and one short (neck) pickup and both can be used as a direct replacement for all Fender-style instruments. All HZ Pickups have EMG's exclusive 5-wire quik-connect output allowing any number of wiring combinations, and are fully shielded for a minimum of noise. String grounding is recommended to further decrease noise.
