Because of more and more cheap but great chinese guitars flooding the market. After so many years of guitar playing I replaced mostly all of my guitars from Gibson and Fender with chinese ones (and I have much much more than in past), e.g. the SGs with maple neck are better then Gibsons. The rest is as good as the expensive ones. Additionally the old rocker generation dies and real guitar heros are missing. New generation players will mostly play modelers and chinese guitars, I think. Refer to

"After the Gibson bankruptcy: guitar makers in crisis
The American musical instrument manufacturer Gibson is best known for its electric guitars. The company has now filed for bankruptcy. The Gibson bankruptcy is just a symptom of the crisis this industry is in. By Stephan Lina. For decades, rock music has stood for dynamism and hope, but the biggest stars of the genre are getting older - and with them the fans. This is a problem for electric guitar manufacturers. The industry thrives not least on idols who motivate young customers to pick up the guitar themselves.
More competition, lower demand
The numbers speak for themselves. Last year, only one million electric guitars were sold worldwide, a third less than ten years ago. In addition, the number of providers has grown. This means that more and more manufacturers are fighting for a shrinking market. This represents an existential threat, particularly for the rather high-priced US providers.
Beginning of an industry crisis?
According to industry experts, Gibson's bankruptcy could be the beginning of a whole wave. Competitor Fender is also heavily in debt; competitor Paul Reed Smith has already had to start a restructuring program. But it's not just the manufacturers who are affected. Guitar Center, the most important retailer in the US market, is struggling with shrinking sales and a growing mountain of debt.

P.S: I also replaced my tube amps and cabs with Fractal ... Things change.
