I have an old Gibson SG bass that's been in a case in my closet for about the last 15 years.When I was using it regularly,I cracked the headstock.I then took it to a repairman,who fixed it.It plays fine and stays in tune perfectly.On the back of the headstock are the numbers 952851 and 'Made in USA'.I believe it's an EB3.It does have the usual wear and tear form being around for awhile.Just wonder when it was made and how much it might be worth.Thanks much.
