I’ve had several SG’s and never worried about the neck joint. Breaking the head off has always been more concerning to me (on mahogany-necked Gibsons). Now that I’m loving my ‘64 RI to death I wonder how true-to-vintage-warts-and-all it is? I’ve never seen a failed neck joint, but there’s a lot of references. Not that I’m worried, I treat my stuff with every precaution.
