First, the Super 70's used Alnico 8 which is a very strong magnet. The distance to the strings is more relevant to the magnet strength than the coil winding. The coils don't "care" how far or close they are... it's the magnet pull that you have to consider. Second, we have no idea what pickups were in that guitar. It's also been assumed that his Ibanez was "stock" at that point and he modded it after. However,
according to Wayne Charvel, he modded it right away (interviewer questions in bold):
...Then going back when we were in our other shop, I just thought of this, Eddie had a brand new Ibanez Destroyer, an Explorer copy. He wanted me to paint it black, but I didn’t have time to do it.
What color was it?
It was natural, a natural color. He said, “Will you paint this black?” I said, “Yeah.” “How long will it take?” I said, “Oh, man, it’s gonna take 3 months before I even begin to get it for you.” I said, “But it’s brand new, it looks great, Ed.” He said, “Oh, I want it black.” So then we moved to the other shop and he came up there. He drilled holes all the way through it. Do you know what a Star guitar looks like? Like an Explorer.
The Charvel Star?
The Explorer is like this, right? He drilled holes all the way down like this, like a shark or something. After he did that, he took a saw and cut through the center of the hole so that he would have a hole like this. When you cut through this half of it, you ended up with this all the way down.
Like a serrated edge?
Yeah, I couldn’t believe he did that to that brand new guitar! It was like, “Hey, if I can’t get it painted, I’m going to do something else.” He just completely thrashed it up.
I trust Wayne's recollection. It's pretty clear, way before they were signed to a label and he was just a kid hanging out in the shop, he was already potting pickups and swapping, so there is absolutely no way we'll ever know exactly what was in either one of those guitars.
