I always assumed that turning the neck pickup on all the way on my jazz would make it sound like a P for decadesThe tone knob is great. I use it all the time to make my J-bass sound like a P. On a P it's also great for cutting out a bit of top edge. EQ is more complex than that.
I never was going to buy a P bass because of that assumption and because I always looked at it as "half a J" soundwise, then Fender/Squier put out this cheap mini P and I said "why not?" and all assumptions went down the drain.
It proved me wrong, with or without tone rolled off. Something about the thump, and of course, subjectivity in sound appreciation, but I like to think that my biases are going away as I am getting older.
