You are right. Fender even has a section on the Fender site where a tech from Fender answers your questions. This is really the same kind of fustration that Mopar owners have. They love their cars but the company that produced them does crazy things now. So they love their old cars and even though there is a new company they get little support from it at all.
The thing is too we all know that a new Kustom could be produced that would be a quality amp and would make money. .
