Fender Japan had a run of fancy guitars called the "Modern" series, and some of them came equipped with humbuckers, called the "Modern Modified", described as "humbucking pickups deliver superior clear & heavy tones while reducing unwanted noise." I'm always interested when Fender offers a PAF style humbucker, as they're usually pretty decent quality-wise.
I didn't open them up, but I popped them out of the guitar to see the undersides, and they appear to be have nice nickel silver base plates. I would guess the covers are nickel silver as well.
The bridge inductance of 7.6H is on the "hot" side, almost but not quite as high as JB, and the neck reads 5.8, also on the high side for a neck pickup. Their description of being somewhere between clean and "high gain" suited seems to be accurate.
