Just to confuse the issue, a stacked humbucker can sound very like a normal single coil because you still only have a single row of pole pieces. Many years ago, I had a 1978 Hondo II Strat copy, but the bridge was like a tele three saddle bridge without the pickup surround. The pickups were DiMarzio stacked pickups and looked just like standard Strat pickups, but I was surprised that there was no hum. I took the pickups out and slid the covers off. Two coils, one on top of the other, and one was reverse wound. The impedance of the neck and middle pickups was 6k, with the bridge being 7.5k. I have no idea what the inductance was.
The most interesting thing was the sound. The guitar sounded just like a 1970s Strat, except the switch was wired for bridge, bridge + neck, middle, middle + neck, so no bridge and middle setting. A wonderful sounding guitar. This model, but mine was blond ash finish body
I've played around with Strat size blade humbuckers - I have two of them fitted on a Squier Showmaster, and while they are more single coil sound than normal size humbuckers, they don't quite sound like single coils.
