I cringed as well, Tom; I mean, preventing that kind of foolishness was the reasoning behind the point in the first place!
David, you are right about single-coils 7 humbuckers - but non-Series Alembics use a whole different animal. There are 2 coils, but only one magnet; it cancels electronic stuff without changing the magnetic stuff.
I, too, (never having encountered an Alembic guitar in the wood) have wondered on the differences in the 2 sizes of guitar p/ups; thanks, Bill.
