I own a Jackson DKMG, double locking trem. I hated the EMG HZ pickups and the 20 decible boost knob. The HZ series is passive and the only reason there is a 9 volt battery in that guitar is for the decible boost. I replaced my HZ pickups with the EMG 81\85 set, which is the set that ZAKK plays. People will tell you that these pickups are for metal only and that's a bunch of BS. I rewired my guitar so I have two volume knobs and one tone knob and I really like it now. Action is low and the neck is slim. I like the width of the fretboard 'cause I have large hands. I bought my jackson off ebay for 450 bucks and it's in great shape. If you've never had a guitar with a double locking Floyd Rose then it may take a little getting adjusted to. It takes longer to restring it and tune it. But they are nice.
