I find it is little more than Odd that every "official" sig pickup of his is 13.5K or higher?
1.The EVH frankenstein (13.7K)
2.PV wolfgang (13.5K)
3.EBMM custom dimarzio (17.8K)
4.the p'u in the Charvel art series (16.8K)
5.His EVH wolfgang pu with fender (14.5)
All of these are at least 13.5K

Just do not see any evidence he was using a lower output PAF like has been rumored all these years.
He himself said he ALWAYS had the PAF's rewound. that alone tells the story if you really think about it and here is why,
if you have ever owned/played on a real PAF it is pretty pointless to take a 8K PAF
and have it wound to 9K(rumored Duncan 78) it does not change all that much.
Not to mention some PAF's were 9K to begin with.
Since they were very inconsistent Gibson was putting all kinds of different resistances in their guitars.
from 7K all the way to 10K.
