Alright, so what if we take a normal humbucker.
And take out the bar magnet.
On one of the coils, put alnico slug pole pieces, and on the other one, put adjustable screws with a small ceramic bar magnet on each side (note the alnico and ceramic magnets will not be touching, there will be a small gap between), put it back together with the base plate, and...
What do you think the outcome would sound like?
Cusp of Magic
Like Morgan Freemans' voice - god-like!
Try it though on a Belcat BH-20 Covered Humbucker Pickup, because they're stupidly cheap (around $12) so you don't mess it up first...
