Yup!
Superpete, have you tried it de-aired, by chance? I like it even better that way!

i haven't! i have thought about it though, everything i've read makes it seems like it'll give me more of what i like. i've only been using an AT1 for a few months now, havent played around too much with it.

yeah, nice read.
well most folks tend to use less gain when they get older. he seems to have done the opposite.
one reason of course it was not possible back in the 70s/early 80s.
well i guess most folks don‘t really care about the stuff after 1984 anyway...

Tony Iommi is the same way...he uses a ton of gain now...much more than in classic Sabbath. My thought is that with EVH, he could make anything work for him. He probably didn't need to experiment as much later in his career because people willingly made stuff for him, which wasn't the case when he was younger.

The Iommi solo album with all the guests on it has some nice tones.

yeah i guess there's 2 ways to look at it...like, he went from Music Man guitars/Peavey amps, to Peavey all around, to starting the EVH line of guitars and 5150 line of amps through Fender. Was it a tireless pursuit of the perfect tone, or was he just looking for whoever was willing to make him the best deal, as he could make the gear work for him because he was Eddie?
i could see it both ways, as i think the amps got better as he went on, but the guitars were never as good as the EBMM EVH models.
I agree- the EBMM were the best guitars. I just think that after VH wasn't a household name anymore, he know what worked for him, and simply had other priorities.
I didn’t want to say anything about Larry dimarzio nice article about Edward but Here is the truth about “Edwards broken pickup” that pickup was giving to Jim Decola by Edward, Jim decola worked for Peavey he designed the Wolfgang with Edward Jim decola knew about the broken pickup before Steve blucher and Larry dimarzio, Jim decola still owns that broken pickup Edward gave him.I’ve spoken to Jim decola many times we have a mutual friend, the winding Jim used on the Peavey Wolfgang pickup were from Edwards “broken pickup”

I'd wonder if the coil exhibiting a ultra high DCR was not behaving also as... a series capacitor.
That's what otten happens IME with a string caught in the pickup: if the wire is broken and stays aligned, it behaves in a capacitive way (generally with a capacitance reading around 4nF while the DCR is either infinite, either ultra high).
If it's the case, the effect should be repeatable with a series cap rather than with a simple resistor. Or at least with a 180k // to a 3.9nF cap.
My two cents (the price of a cap).

To illustrate my reasoning process, I post below some sims that I've just botched.
Pic 1 shows the response of a 'Hot" HB with its first coil @180k.
Pic 2 shows the same thing with the second coil @ 180k.
Both show what happens if a damaged coil is purely resistive: it behaves like a limiting resistor, IOW like a lowered volume control...
Pic 3 shows one of the coil @180k + series capacitance of 4nf. In this case and as expected, the series capacitance is "reEQing" the pickup without altering its output level.
It scoops the mids because the series capacitance follows coil1. If series cap was after coil 2, it would cut the bass and bump the mids.
Again, FWIW: a nerdy attempt to share. ;-P
NOTE - I won't reveal the PU model used for these simulations in the name of intellectual property. Thx for your understanding. But I can tell that it mimics faithfully the behaviour of a "hot" HB + 4 wires cable.
EDIT- Below is the response of a Duncan Custom with a broken capacitive "coil 2" (pink and black lines = responses of each coil), compared to the response of an intact Duncan Custom (green and white lines). This time, it's a real measurement and not a sim.
The pickup was still working... as a high pass filter.

Yes.
In my simulations, the responses of the two coils are merged together.
In my measurements, the responses of the coils have been measured separately.

Yes it would but it has not been done and the broken pickup has been repaired in the meantime.
Now, if we follow the upper lines for each pickup, it will draw something looking like the "merged" responses of my simulations...

Yeah, They do go back and forth on it, actually at one point in the mid naughts had it as the Breed and Air Norton. I'm more inclined to believe the breed is actually the closest you can get regarding the raw materials and wind than the AT1 is, the AT1 is similar enough, but uses a slightly different wind, and a nickel plate which isn't as lossy. The breed seems to check all the boxes in these areas (approx symmetrical 7500 turns of 44awg each bobbin, AL5 magnet, and brass baseplate) I think if you were to drill out the north bobbin of the breed and stuff it with slug poles, and then swap the allen poles for fillisters in the south bobbin, you would have an axis, complete with the spray painted brass base plate. The issue though, is that most people are likely not going to risk trying this. I think if I found an extra one around for cheap, I would try this just for giggles.

Freefrog, for context, what was your testing methodology?

Hello,
In the pic above, an ultra low impedance air coil has been used to excite the pickup with a sweeping signal. Its response has been captured through a classic wiring harness + cable + 1M input.
it's the old method popularized by Helmuth Lemme, and that various people use around the World, with variables testing rigs.
That's all I can say on a public forum.
