Neodymium magnets from what I've read are the strongest permanent magnets around. Correct me if I'm wrong, but doesn't a stronger magnet mean a higher output? I've been looking into it and custom made neodymium magnets aren't that expensive to produce on an individual basis.
How hard would it be to replace the magnets in an existing pickup with neodymium ones? Has anyone experimented with this yet? If so, how did they affect the tone of the guitar?
