Fender was set up for mass production from the first moment, tone was secondary and this tends to get forgotten amongst all the vintage hype. Fender had the production values similar to many far eastern factories today. That some of the basses sound good is probably a happy accident due more to good engineering than materials choice.[/quote]
True, but it became expensive in the 70s and so they moved to the cheaper closed grain ash.
You could probably debate what people thought sounded 'good' back in the 50s. I suspect sounding like an acoustic bass was the original aim. But since they were first with mass produced instruments the Fender sound has obviously became the sound that people expect from an electric bass.
