The EMG F-H3 guitar pickup uses two stud piece loaded coils for better noise rejection with over wound coils and a ceramic magnet. This pickup uses the 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. The F-H3 has Floyd Rose pole spacing of .410" (10.41mm) string to string.
