I would sincerely be interested in hearing more about this, if it is something you can share. I have no idea about where automation is/isn't used in this process. Labor is obviously a factor (Asia vs Mexico vs U.S.).
Related to the above, I would also appreciate your insights (or speculation) on how Fender can offer more options on basses and Gibson can't. Is it due in part to gaining huge and permanent marker share being one of the first entries in electric bass market? [Note: I am not trying to be contentious here. I really am fascinated by this "stuff".].
I once met a gentleman, who had been with PRS guitars. In his opinion, he thought it was a mistake for the company to offer their entry-level MIA. He thought they should have stuck with their high-end MIA and Korean-made lines. He thought Korean and entry-level U.S. would eat into sales of high-end MIA. He also confirmed what some of you have mentioned: 80/20 rule - us "oldsters" buy several instruments AND the higher end models ('cause we deserve it, damn it!).
