Floating vs. Set Humbucker tonal differences?

[Marty Grass]

FWIW, The Heritage Super Eagles with set in pickups have thin tops when compared with, say, Gibson L-5CES or Super 400 CES guitars. Still, they are structurally stable and don't feedback badly. They also sound GREAT.

I think you are right. But there are exceptions. Gibson can be somewhat variable, especially the older ones. Heritages are even more variable. I don't see that as variability in quality really, just variability in character.
