GuitarDoc,
You are incredibly negative in most of your posts. You act "as if" you know more and are better than everyone else.
Lowering the charge of a ceramic magnet might have an effect that someone would desire. Like a way to lower the output of a pickup and slightly alter the tone.
How would you know if I want that? There is no way you would know what I want or am trying to achieve. You need to check yourself and your attitude.
