I know this has been discussed before - on both the electric and upright sides - as well as w/ fiddles. And my understanding is that some people feel a stringed instrument continues to "get better" beyond some relatively short breaking/settling in period, with little real support either in experiment or rational theory. I've been surprised at how many threads recently have made reference to decades old instruments having "opened up" and such. I find myself dubious to such claims. -I can imagine that many older instruments that have survived might have been the better sounding ones when they were young. They were cared for better and valued more. -I can imagine a single owner becoming increasingly in tune with the specific characteristics of an instrument, such that they can get more out of it. But I can't figure out a reason to think that - say - a quality 50 (or 150) year old instrument would sound better than it did after 5 years of playing. Anyone ready for another go-round?
