My father recently passed away and I have his electric guitar in very good condition. I can remember him playing it when I was little so I know is at least 30 years old if not more. The serial number is 76879. I believe its a Sunburst.
That’s a pretty cool model and a great heirloom. Looks like one of the old Les Paul models. These were built predominantly in the eighties and nineties. Maybe even earlier. Normally the first two digits of the serial number represent the last two digits of the year. That would mean the model is from 1976. However, the serial numbers has few digits. Probably the 8 is already faded and the model is from 1987.
