hi guys, Ive looked ALL over the place, and cant quite find what im looking for. I have just purchased a beautiful Jackson C20 concert bass from CraigsList. the guy said it had been sitting in his fathers storage for about 4-5 yrs.. couldnt put an exact yr on the original purchase of it. now, from what i understand, the "serial" number or production number cannot tell you a yr or sometimes even the place it was made. my question is, IS there a way to tell the yr that they were made? or am i stuck guessing a timeframe of make?
