Remember, these are guidelines, and until you experiment with different types of magnets in the same pickups, you won't know their general effect. Comparing different magnets in different winds doesn't make a whole lot of sense with out taking into account other factors.
In other words , maybe swap out magnets on one side ( Half ) of a Humbucker . Something like half A5 or A8 and half Ceramic ?
A number of humbucking sets use ceramic in the bridge pickup and alnico in the neck. It's pretty unusual to see a single humbucker that has both.
But I believe the Mojotone Black Magic humbuckers are made using a combination of ceramic & alnico in each pickup.
I'm not a high gain player myself and I've only been able to really bond with a couple of ceramic pickups, though I remember liking the DiMarzio Super D back in the 70s. Two modern ones that I have enjoyed are the standard Duncan Custom (but I will say that I like its alnico versions also) and the Railhammer Chisel.
Another is the PRS Dragon 1 bridge; I have two of those. The Dragon 1 is super overwound- quite full and compressed, with lots of midrange. Warm and fat, not well defined on cleans or particularly responsive to nuances of pick dynamics and fingertouch. There are those who would call it congested but you have to treat it for what it is and use it for its strengths: it's a really great pickup for high gain lead tones. Not a pickup that suits my overall style, yet nice to have in my arsenal for certain stuff.
That Dragon I set was my first experience with alnico 4. The 8K neck pickup is alnico 4.
I liked the neck pickup.
But the 18K ceramic bridge pickup was way too hot for my tastes.
I have a modified set of Duncan 59's in that '95 PRS CU22 guitar now...modified with Roughcast Alnico 5.
What are the main differences between the two, do ceramics genrally sound harsher and cheaper than alnico (specifically Alnico V)
wadr ~ That is probably true for someone who is trying to get to know their guitars , lets say 5 or so and get some Variety and personal Sound Style established . After changing out almost countless pickups over the years and builds , Recording , Live Performance ( Most Important to myself ) - I would pretty much KNOW what I am going to Get with all of the properties previously Experienced in a Swap out , as an End Result on quite alot of configs . but You guys Always get the Cobwebs knocked off and get the wheels Turning such as this Here --> What May be killer + I've Never thought of is combining Alnico with Ceramic on the Same Pickup( maybe it could make big $ ; ) and making a hybrid pickup with both , could work Awesome in a few Configs .
