I bought a used Les Paul custom. Can't figure the serial number out. I'm pretty sure it's no more than a few years old cause it's in amazing shape. Eight digits: 08008083 It's impressed in the headstock, not stamped. According to Gibson site, the 1st and 5th #s are the year and the 2nd, 3rd, & 4th #s are the day. But there's not 800 god damn days in a year. Any ideas? Maybe they changed the order of the numbers?
