I know their P-90's have ceramic magnets.
I have a Nashville pickup that I cannot find a mounting ring to fit it and they don't offer one. If I ever use it, I will probably have to body mount it.
I love the HV58 set I put in my Epiphone SG. I did replace the covers with raw nickel covers from mojotone music.
The noiseless strat set is very impressive as well.
And that may be something I won't care for as much but I won't know until I've tried them. Ceramics can sound great when they're done right and maybe these fit in that category.
