Anybody using Iron Gear pickups?

I've just put a Tesla Shark on a partscaster I've built; it sounded pretty good through a Boss Overdrive pedal.

Curiously, though, the two single-coil Strat pickups (middle & neck) I put in are as loud as the Tesla Shark; I'm not sure what they are, but they're just stickered "Made In Japan" and have a really good Strat sound.

The guitar also has a Floyd Rose "Licensed" trem, which seems OK, apart from the arm mounting sub-assembly failing within days (now replaced with a Schaller component to replace it and that's better).
