I know it sounds odd, but the closest BKP's to the Tone Zone kind of EQ I've tried are the Miracle Man and Warpig neck versions
and the MM neck works really well in the bridge position
FAT, powerful and very fluid
darker, bassier and more nasal than the Holy diver, but that's how I'd describe a TZ too
and it has around 17.5k, alnico 5 magnet, just like the TZ
I suppose the Air Zone is like this too
but I wouldn't do it in a LP Custom anyway
the Holy Diver is the Rebel Yell bigger brother, so I don't know if you're going to be happy with it if you're not liking the Rebel
maybe you should try different amps and settings, maybe speakers
the main thing is that his guitar is alder with a very dark pickup, so he has that bassy hollow tone
if you put a pickup that strong and dark in a lp custom, you'll get a MASSIVE sound, very different from his
maybe if you try something less powerful and middy... maybe an emerald(?)
