I had my Charvel equipped with EMG 81/85s for decades and really liked the defined and tight sound for extreme metal. Now I got a bit older and missed some tone, feel and low mid punch for that not-so-scooped metal sound. I bought a JB/59 pair and I am totally happy with them. I'll never go back to my EMGs, which BTW sucked big time in the neck position (both 89 and 85s, OK the 89 was OK in coil-split mode) because they are muddy, undefined and boomy as hell.
