I don't understand the mentality of anyone who buys a specific instrument known for a specific sound and then immediately modifies it to try to turn it into something else. Doesn't it make more sense to buy the "something else" in the first place? When I want to play a passive bass, I pick up my P. When I want to play what amounts to what was designed to be an active P replacement, I pick up my 1980 Stingray. When neither will do, then it's time for the JB. Isn't it supposed to be about picking the correct tool for the job? (I also play a 5 and an upright.) Don't ruin a perfectly good instrument that might be just perfect, as is, for someone else. Sell or trade the 'Ray and buy a P or whatever it is you actually prefer. In the long run, that's to everyone's best outcome, including the bass itself. In over 40 years, the only things I have changed on the Stingray are the strings!
I also don't understand the "too many knobs" argument. No matter if I am playing passive or active, I start with everything flat, and make minimal adjustments until I have what I want. I also don't wait until the day of the gig to start figuring out what all those knobs do. lol.
Regarding mods, you can't make a lousy sounding bass sound good by installing an excellent preamp or a massive bridge, or lighter machine heads. In my experience, the best thing you can do is buy the best bass you can afford. The better the instrument to begin with, the less likely you will feel the need to modify it, and the fewer mods you will feel like it needs. Just my 2 cents (over 50 years playing experience).
