If you’re handy enough to replace your own pickups, you can “air” the magnet of the Norton and see for yourself.
There are decades of marketing mumbo jumbo clouding info about the Air pickups, but I don’t think anyone will disagree if I describe the mod as decreasing the amount of voltage the pickup is able to induce. I would say that, yes, aired pickups exhibit a softer pick attack as a byproduct of this; as I’ve previously A/B’d recordings of a pickup that’s been aired against recordings of the pickup without the mod, but lowered away from the strings until it has a similar output. But those recordings are long-gone, and I have only my faulty memories for reference.
