The EMG-H4 BLACK - The H4 is the equivalent of EMG's 81 Active Pickup without the "Active". It uses two bar-loaded coils for that "Balls to the Walls" tone. The EMG-H4 pickup has become the bridge pickup of choice for the ESP Guitar Company. 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.
