I wouldn't take those mV values seriously. DiMarzio doesn't reveal what methods they use to derive the mV output. A pickup doesn't have a fixed mV output, the voltage output is dependant upon many factors, such as how far the pickup is from the string, how hard you strum, and how permeable your guitar strings are. To assign a fixed mV value to a pickup the way they do, is strange to begin with.Antiqua, you said and I quote: "The EJ Custom bridge really is a HfH in a different package. Where are you getting the impression from that they output is different?"
Well, that is in fact http://www.dimarzio.com
Telling me the EJ custom Neck (DP211) has output rate of 178 mV (DCR 7.01 Kohm)
And the Humbucker From Hell (DP156) has output rate of 226 mV (DCR 5,89 Kohm)
So going with the output rate, it tells me that the HFH has more output.
I've actually studied and used both sets extensively:
Humbucker from Hell
EJ Custom set
The inductance of the EJ Custom and the HfH are nearly identical, at 2.3 henries, and both use AlNiCo 5 1/8" bars, and both conform to the same PAF layout, so there is no mechanism through which one of those pickup can produce a tone that is much different from the other. It gets to that point where you have to decide if you believe the hype, or if you're going to stick with science.
As an aside, you will notice that the HfH has a lower DC resistance, the reason for that is that DiMarzio patented the bizarre practice of mismatching the wire diameter of two coils, while retaining the same number of winds. There is no known benefit to be had by doing such a thing. I took a picture of it here, you can see the cream coil is more narrow. The black coil is using 42 AWG, the cream 43 AWG:
The EJ Custom shows a higher resistance because both coils are wound with 43 AWG (possibly 44AWG), the especially thin coils can be seen:
If you read the product description and "tech talk", none of this is mentioned, though if you look at the HfH product page, http://www.dimarzio.com/node/2142 , the patent number is listed where in DiMarzio tries to claim there is a benefit to mismatching the coils "Patent: 4501185", which you can reference with google: https://www.google.com/patents/US4501185
When it comes to technical details, most all of the pickup makers play fast and loose with the facts, they would rather sell the pickup with words. DiMarzio says "This pickup is the cure. With some guitar/amp combinations, it can sound almost acoustic. With others, it's real Strat®-like" They'd rather not say "it's the EJ Custom with hex poles instead of screws and slugs", for obvious reasons.
