from both sound and spec, I'd say it's kinda somewhere between the holy diver and the black dog, but more balanced than both, and yes, could be compared to a 498t or custom 5, but actually pretty good sounding (not a fan of the 498t, and duncan customs are too compressed for me)
it has a chunkier but tighter low end response than the holy diver, but less compression and a bit less pronounced mids
I wouldn't compare it to any kind of PAF
it's a hot rod medium-high output humbucker, but not a hot PAF
I mean... it sounds more like Jerry Cantrell than like Page or something
it delivers a big crunchy tone with lots of sustain, but not as smooth and compressed as a holy diver, not as open, middy, bright and tight as the rebel yell
it's more balanced through frequencies than the mentioned models, although I prefer the extreme mids of the others
the neck pup is quite different, though... more of a dimarzio type voicing than gibson, maybe(?), but also pretty balanced and not really PAFey nor ultra modern
