I'm going to be controversial and say that personally, I think G guitars are overpriced lemons, I've got a 2013 genuine USA made G LP Studio, it has always been a pain to keep in tune no matter what I've tried, tried all the usual fixes and they didn't work, tried replacing the hardware with better hardware, didn't work, I'm done with G guitars.
The only good thing about G guitars is that they look good, and that's basically it.
And to be honest, my genuine F guitar isn't any better.
