In many ways i agree with Grover's statements about Fender.
Leo Fender WAS a genius. He figured out how to make guitars in a way that nobody had really thought of before. The Telecaster was brilliant in its simplicity, and the Strat nailed so many things… the ergonomics, the way the trem worked… it was darn near perfect when he designed it. But then they sort of sat on their laurels and kept making the same thing, and didn't really improve or refine it. It took guys like Grover to take the Strat to the next level of evolution, and the rest is history.
It's also important to keep in mind that the CBS era is arguably the low point in Fender's history, so the bar was set pretty low. Jackson/Charvel changed ownership a few times before Fender snapped it up.
