who woulda thought that a thread about Fender basses could get so contentious?
I haven't owned a Fender(tm) proper in a few years, but I do own a Jazz style bass that is everything I wanted in a Fender J, or a P for that matter. As much as I love my Sonus 5, it isn't the right bass for a lot of things. As someone who works on my own material, plays on others material, and does a fair amount of mixing and fixing, there is a reason why some basses work. Most of the time you want the bass to occupy a certain piece of the sonic spectrum, and present the fundamental without distracting from other areas of the mix, and some basses are right and some aren't. That changes depending on the style, the instrumentation, the player... If I had to pick up one bass with the best chance of being "right", it would be the J (a Jack Read custom with Bart CS stacks, VVT, passive). It can cover a lot of ground, and still be plenty bright even with the old TIJF strings that I have no interest in swapping out.
If it had to be more upright-like, I have a Tacoma ABG. If it had to sound super detailed with more high end or something that I would rather do with an active bass, the Zon. But still, The J just kills on most things where you want a bass to sound like a bass. The track needs little or no post processing.

I feel like a broken record on this, but here goes: Most bass players think "their tone" is the axis on which the music revolves. 99/100, it isn't. Spend some time behind the desk on a variety of projects with a pro and you can find out what makes or breaks a bass sound. Most bare bass tracks sound (to the player) horrible, but sound great in the mix. It has a lot to do with psychoacoustics and human hearing, IMO. Most "idealized" bass sounds are pleasing in the bedroom, but are awful in the mix. Likewise, many (maybe most?) of the bass sounds that you like don't sound the way you think they do if you hear them on their own. I'm not saying that you shouldn't have a sound that you like, but I am saying that it is far less important than you think it is unless you are recording solo bass, or lead/feature bass... and even then, the player is often the last person you would want behind the board. I've had a chance to work with a few good engineers and they have been consistent: if the player insists on using some bass with a bad/wrong tone, they are thinking ahead to how to fix it. I guess it comes down to the things that happen when players who play for a living work with engineers who engineer for a living (and I am neither). i.e it is very common for good engineers to go out into the live room and show experienced drummers how to tune their drums and they don't expect any prima donna act, and the same goes for everyone else.
And remember... this is one opinion based on one set of experiences. If you don't agree then you are certainly not alone and I don't take it personally.
