fender & gibson were subjected to changes of ownership and/or disasterous self-undermining own-throat-cutting marketing decisions and manufacturing economies..
guitars from that period are considered by age to be 'vintage'.. dealers try their luck to get vintage prices for them.. despite the problem that fender/gibson guitars produced in that era are very variable in quality and widely considered the worst made ever instruments to be badged with those companies honourable headstock logos..
so.. whats to prevent similar corporate business suicide marketing strategies being inevitably inflicted on any other long respected US guitar brandname..??
Btw.. if memory is correct.. in the early 80's fender, desperate for survival and in need of emergency help to restore their failing reputation and turnover, bought in valuable aid and advice from yamaha guitar product consultants..
