I over analyze so many things in life. I can't help it, it's how my brain works. It's why I get paid to analyze things. I've read a lot of mentions about some acoustic guitars. Lots of "the more you play it the better it sounds" and "playing it a lot will open the pores and sound better". Speaking solid wood of course, not laminate, and I mostly hear this about acoustic. Is there any science to that? I know wood changes a lot with conditions, be it humidity or temperature. Wood flexes, it bows, it shrinks and expands. I know for damn sure whenever I buy wood for a project I pick the straightest boards and within a week they're curled no matter how I store them. I can't imagine wood being vibrated "a lot" leading to pores opening or tonal qualities improving. Does the guitar actually make a "better" sound after years of playing it? Or are people hearing the result of playing for years and becoming more skilled at guitar? If the guitar gets better, why wouldn't factories build a machine that strums guitars 24/7 for a few months to simulate a well played guitar? I'm a car guy and I make a lot of car references. It reminds me a lot of hearing "this muffler sounds killer once it is broken in". Most mufflers have nothing to break in, they aren't packed with fiberglass these days, they are perforated or chambered metal. Nothing changes, you just get used to the sound. Not trying to be smart here, just very curious if it's a real phenomenon or a myth.
