I've recently been pulling out some of my guitars (PRS) for basic string changes etc. that are now 15-25 years old. That's since I got them new. I've now gone through about 8 in the past week. I could swear they all are sounding better than I remember. So I started thinking about old wood, internal resins changing/crystalizing over the years. Or is 25 years too short a time to make any difference. And maybe the stories of older instruments' tone improving over the years makes sense. I'm definitely far from a wood expert. I wondered what others' experiences in this have been.
