hi softies, hope you can help me out with this. i saw several gibson les pauls made from different years, both standard and classic. i found out that some standards have Chromed Grover Tuners with the kidney bean type of tuning keys instead of the current green ones that we see. Also, for some les paul classics, the headstock does no say "Les Paul Model". instead it is "Les Paul Classic". i want to know why are there these differences and im rather curious about this.
