I think all my stuff sounds great. Haven’t bought anything new in a couple of years now.
Actually, I’ve been in more of a "selling off the excess" period, getting down from all sorts of stuff I’d acquired to only the stuff I’m happy with (which is still plenty). Meanwhile, there are certainly other good and interesting tones and sounds out there to be had, but I simply don’t need to own them all. I’m basically a P bass guy, anyway. P and rounds; done

I figured that out with my second bass, 20+ years ago. Then I got into short scale and got those sorted out by about 5 or so years ago. My acoustic basses are completely satisfying to me…
Then, besides having more basses than I need, I’ve got a pedalboard full of great sounding effects, most of which I don’t even need.
But, even though I am "in love with my tone", I could still do with one more amp for a change of pace (something with some lightish tube poweramp overdrive available would be cool) and more volume (if needed, which it currently isn’t), and maybe some kind of tube DI or some kind of great sounding amp emulation box for easy recording. But… I dunno, I’m not saying I’ll never buy any bass gear ever again, but I’m not itching much for anything, really. Overall I’m very content and have been for a while now
