The C++ sound is cool, but the fact that it shares 95% of it's DNA with a C+ makes having two separate models nothing more than overt, unmistakable greed.
Of course Gibson's number goal is to make money, but not having a switchable C++ mode available on the C+ is next-level disdain for their customer base. Maybe next they'll produce only single pickup Les Pauls, and you'll need a pair to cover both neck and bridge tones.
After hearing and owning a bunch now, I'm also a fan of the 60's. There's still plenty of punch, but they're a tad more focused and immediate.
