I put brass ones with pretty pearloid buttons on my J-45 at my first string change 19 years ago, I doubt it did more than lighten my wallet.
2 years ago I put the original J-45 pins on my Fender Sonoran, I doubt it did much good there either, but it gave me something to do. Not sure if those were bone or plastic.
Now I have a set of black plastic Fender pins with a while dot on em I need to buy a guitar for.
It’s a viscous cycle we can never escape.
