Yesterday, I was polishing my masterbilt when I noticed two small hair line cracks in the back one less than inch the other a little larger. Then I found one on the top that ran from where the neck meets the body to sound hole. I'm getting a little worried that I am about to have some major issues. I keep it on a stand all day when not playing and I always have one of those little humidifiers hanging from the strings. How concerned should I be about these cracks? Anyone got some input.
