The EMG H4A uses an Alnico 5 magnet for a pronounced mid-range and fat top end. With plenty of punchy tone, it's perfect in the bridge position for the player who wants to rock. The H4A is the perfect guitar pickup for blues or in combination with the H4 pickup, as is used on Epiphone's Zakk Wylde "Bullseye" Guitar. 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. Features & details EMG H4 Passive Humbucker Bridge Pickup Black Cover with EMG Logo Includes Quik-Connect Connector Two Year Warranty
