Not sure if this is the right place to post this, so sorry in advance if it's not.
:?
I was wondering about pickups and magnets. What would a Samarium Cobalt pickup sound like? A neodymium pickup? Is that another word for ceramic types? Rare earth magnets?
About humbuckers, I'm lost, I know ceramic pickups have the magnet on the bottom and the pole pieces are attached and the magnetism goes through those, on a single coil alnico pickup the pole pieces are the magnets themselves. Is this the same for alnico humbuckers? If so I wonder what a hum would sound like if say the top 3 were alnico 4 and the bottom 3 were alnico 5 and the other 6 were alnico 2, you get the idea.

Nearly all humbuckers have the magnet underneath the coils in the centre where both coils meet between the screw polepieces and the slugs. This way the screws are one polarity and the slugs are the opposite. The only pickup I know that was really different to this is the original PRS, where the slugs are magnets.
Also P-90's have the magnets underneath and the screws conduct it through the coils. In this case (and with some high output single coils), there are 2 magnets, one either side of the screws.
You could only try your idea in a single coil, like a Strat. I had a similar idea last year, but using a mix of Alnico IV and V and changing between the bridge (E,A,D,G -V, B, E - IV), middle (E,A,D -V, G, B, E - IV) and neck (E,A -V, D,G,B,E - IV). Tim has done some experiments with it I think, but I am not sure how it worked out.

bump :D

Sumarian cobalt and Neodynium are very strong, but very cheap and are used by some comanies because of this. But unfortunatly they sound bad too!
All humbuckers are made with a bar magnet down between the screw and slug coil, some have been made with magnetic rod pole pieces, thats the only way of making mixed magnet humbuckers.
-
Well what about when on a strat when there is a rwrp with the middle pickup? wouldn't putting those 2 together simply make a 12 rod humbucker in which magnets types could be combined?
-
yes, you can, but the strength of 12 magentic rods tends to mess around with the tuning and sistain of the guitar by pulling the strings too much.

Oh..hehe..gotcha.
Hey thanks man. Sincere appriciation for the replies and for not laughing at my stupid questions.

Harry Haussel does such pickups for strats and teles:
