Hi Mojo, funny you should mention CSI because that is where I work; really, it is.

I think you are correct about the Screamin' being ceramic & the Dry being Alnico, from post I have read here on the TF.
......... the only reason I took the pickups to work is so, I could trim the leads under a scope.
It works great
I could actually see what I was doing :lol:
while I was at it I looked at the two sets of pickups, and I noticed the color of the magnets, and to my surprise I noticed the pickups were actually potted
to some degree.
To actually see the magnets, and also to see the potting material that has worked into the spaces near the slugs & spacers, the covers have to be removed.
The Double Tricks are from my 1982 MSV-850 so, they never had covers.
The UDs came out of my long gone 1980 EG-450; I removed the covers because they are going into the MSV so, they had to look the part.
The guts in the UDs
look just like the DryZ set in the below link; wood spacers and all, except the magnets are charcoal black, not silver metallic.

Check the second & third photos of the ends of the magnets; clearly Alnico.
I think member japanstrat mentioned that the ceramic pups may not even read/register, if I recall correctly.
I have never put a meter to any of my pickups ...................
I have a set of PU-0, a set of PU-2, two sets of DryZ, the Double Trick set, two or three sets of Screamin', and a set from an '89 EG that I assume are comparable to the Screamin' pups.
