The F-H1A pickup features the same design as the F-H1, but incorporates alnico magnets instead of ceramic. While the H1A pickup combines EMG's traditional internal design with adjustable pole pieces and over-wound coils, the result is a much warmer sound with a pronounced midrange 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. The F-H1A has Floyd Rose pole spacing of .410" (10.41mm) string to string.
