The bass cab industry is a rather small player in the neodymium market, and we can get by with ceramic magnets if we have to. Other industries are going to be much harder hit.
It will take about two years for new sources of neodymium to reach the market in significant quantities, and that may not restore stability to the market. Right now China holds most of the cards, and will be in a position to crush their fledgling competitors with low neodymium prices as soon as they begin to produce. So in two years we might see teh beginning of a period of low neodymium prices, followed by skyrocketing prices once China's competitors have been put out of business (which is precisely why the Chinese neodymium industry has no competitors today). I've seen that sort of thing in another industry that I was involved in at one time, and in that industry the big player didn't have nearly the position of power that China enjoys in this case.
