The SJHZ pickup uses a stacked design with ceramic magnets and a laminated steel core for increased output and lower noise. This pickup is for the neck position in a standard 4-string bass (or a narrow 5-string bass) and acts 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.
