The H1A Pickup features the same design as the H1, but incorporates Alnico magnets instead of ceramic. While the H1A pickup combines EMG's traditional internal design with adjustable pole pieces and overwound coils, the result is a much warmer sound with a pronounced mid-range and less top end. 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.
