Sometimes you play a bass that defies all logic and just feels and sounds right, be it vintage or new. There’s no shortcut to the top - just get one you like the look of, used, and try it, then get another and compare, keep going and many years later when you’re living in a shipping container you’ll reach the final level. Then someone suggests flats and you start all over again. It’s fun, honest!
Side note - don’t limit yourself to Fender although definitely try some of those too!
