They started doing weight relief because in the Norlin era they were getting out of hand, like 10lb was normal, 11 or 12lb guitars were not out of the question.
Their naming really confusing, you'd think they leave Standard as Standard, and then any wacky ideas they would put it into something like the modern line.
Except they had Standard, Traditional, Classic Performance and whatnot all available at the same time. Out of all those only the Traditional is typically the old spec, the rest had weird switches, I think the Classic once had a boost switch where one of the tone knobs would be with a battery inside. I mean really?!
And yes, my CS cost me £2k all in after part-ex with the value of what I paid for the guitar that I part-ex with. It could cost another £1k+ more now to get it again.
