One thing that folks need to remember about a big company like Fender is that even their top of the line handwired boutique stuff still needs to meet all the worldwide criteria for safety and green/hazardous material standards. Making these amps in California would/will add even more cost and little gadgets like thermistors and other safety devices that weren't in the original amps. The certification alone probably costs more than most people would expect. This is part of the reason that smaller, under the radar, builders can keep costs down on similar items. A lot of the time costs go up as a company gains some ground in being able to legally market their amps overseas or begins to sell a lot of amps to buyers outside of the hobbyist market (you know, those folks who will stick metal objects inside speaker and input jacks and then sue). Fender and other large corporations have a lot of CYA stuff to protect themselves, their employee's jobs, and their investor's money against.
