Difference between pre-eb and stingray HH

What realistically is the difference between the 2h and the pre Ernie ball Sabre? I heard that sterling was talking about trying to solve some of the issues with the Sabre through the sterling way back when and was interested in what he said there.

I know the differences between the hh and the Ernie ball Sabre are pretty big, not many 16 pole piece pickups out there, but shouldn’t the hh be very similar to the pre-eb Sabre?
