That's exactly their point. In John Hall's interviews, he always states that RIC won't go down that road. They simply don't want to be bigger and have to move production to overseas, offer cheaper budget brands like Epiphone or Squier, and so on.
Me, I admire them. All their guitars are made in California, there is no proper "low end" or "high end" model, each one being close to unique, and they also don't have a boutique called "custom shop", like Fender and Gibson do. Makes me think of what Fender was all about back in Leo's days.
Even proper custom instrument orders are very rarely taken. And they actually don't sell the reissue/vintage fad. If asked, they'll tell you that modern Rickenbackers are just as good as the vintage ones and probably even better.
As for the necks and fitting big guys' fingers, there are several models with wider necks.
