There are only 2 big companies with big names, but I think you are seeing a paradigm shift with respect to guitars. Younger players, in my generation anyway, are much more open to the up and coming companies, many of which nowadays are built to absurd quality standards. I would lump these guys to anything post 1980 even, it just takes time. All the old farts can't be bothered by them, as they have found soemthing that works, and for the most part guitar players are pretty static in their wants, afriad of too much innovation. A lot of it seems to be what music you listen to, and who you saw with said instruments growing up. Communities like the metal community are much more open to other brands. Blues players by and large are stuck in a big classic rut (like their riffs, also 20+ years old

). There is always that lingering belief that the guitar itself holds some kind of power, not just the player who used it, which I believe is an extremely misplaced thought. But look at guys like Knopfler, playing Suhrs nowadays, instead of his classic strat.
Classic rock also seems to possess a lot of that need to remain with the classics. I put this back once again, to believing the guitar is more than it is. These companies just need to stick around a little longer. I have a custom incoming in 2 weeks from a shop that isn't even full time for the owner, should be by the end of the year though. The industry grows, as players demands change. Small time custom shops are getting a lot more common, and players are starting to learn they do not need to settle for less than what they actually want. This all compounds the shift.
