I am thinking of adding another bass to my gear. I have a Kawai F2B with active pickups, and a '72 fretless P bass. I am thinking of a newer Fender fretted bass though I'm not sure P or J yet. My question is: What are the differences in quality between U.S. or Mexican or Japanese or wherever built basses? Is it worth it to spend the xtra $$$ for American made and why or why not? I am an adult in a cover band for fun and a few $$$, and we all have professional gear.
