Can the serial number of a Les Paul (in my case #02234649) determine whether it has a 50's or 60's neck? I think the serial number number indicates it was made sometime in 2004. All I know that it's a Les Paul standard. The neck feels great. The salesman told me it was '60's neck, but since I bought it used, who knows if he really knew. What are the differences in necks on Les Paul standards nowadays?
