I also feel my basses changing as the years progress. Especially the more they're played. My Stingray, which I purchased new in '20 and has been my main axe since, has gotten lots of use. And sometime last year it changed subtly. It's a little warmer, softer, certainly easier to play. After changing strings and whatnot, I can say with confidence it's the instrument.
But, I'm in the minority here on TalkBass. I think wood matters. I think instruments break in and change with time. That's been my experience at least. It sounds like it's been yours too. That's okay.
Don't mind the naysayers. They spend more time on the forum than in the practice room anyway.
The use thing is real. Its like a car.
The wood aging is suspicious.
