Good thread here! I have also changed from plastic to bone on my guitars in the past. Last week I bought a new J 45 Standard at GC, complete with Elixir nano web lights (12 - 52) 80/20 phosphor/ bronze strings. Had not been a fan of Elixir prior to this but these sounded really good. In fact the guitar sounded awesome new out of the box except for the string change they made and a neck adjustment I had made to lower the action a bit.
After reading through this thread I was thinking "yeah, change to bone and get an even better sound". I asked my luthier about it. He's worked with me for several years and knows the sound I go for but in this case his advice was don't mess with it if you like the sound as it is. I'm considering following his advice in this case because this is the best sounding acoustic I've ever owned and sometimes the changes I've made in the past didn't have the impact I desired, sometimes even being negative. This guitar's tone is so well balanced as is that for the moment I'll probably leave it alone. I may swap out the pins on the next string change to get bone with abalone inlays but more for appearance than anything else.
So this week I've learned to bend the rules some and leave well enough alone at times. But to each his own!
