Like the H3, the H3A uses two stud piece loaded coils for better noise rejection with over-wound coils and a ceramic magnet, but incorporates an Alnico 5 magnet for a warmer sound with a full top end. This pickup uses EMG's traditional solid cover cap in a unique HZ design. 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.
