Petite info sur les Jackson (DKMG ...etc) c'est des EMG HZ-H3, et pas HZ tout court c'est marqué sur l'arriere des micros.
Et il doit pas y avoir une grosse difference avec les emg H4.
D'apres emg:
EMG H3 :
The EMG-H3 uses two stud piece loaded coils for better noise rejection with over-wound coils and a ceramic magnet. This pickup uses our 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.
EMG H4 :
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.
