I've had My J-15 for almost two years. I haven't properly humidified it(I really should) The humidity in my house is 20%. It hasn't fallen apart and it shows absolutely no indication of not being properly humidified. A couple of times I banged it with my heavy brass belt buckle, Not a ding on it. The walnut used is fine quality. You mentioned the tuners? What's wrong with them? They're well made and do what they're supposed to do which is accurately tune the guitar. You seem hooked on "more expensive better" "less expensive bad, inferior" people tend to do that to make themselves feel about their own stuff. I bought the J-15 because it sounded better to me that the other guitars in the shop that I played, including other Gibson's. I once owned a Martin cherry SWD which was a fantastic guitar. Is cherry an "inferior wood"? Saying that a J15 is an entry level guitar is incorrect and getting caught up in "this is the only way to cut wood" seems silly. And the price point is due to to curent supply and sustainability.
