I have a 1982 Epiphone Spirit. I have had this guitar for a good many years, and recently learned it is rather valuable. There is something rather odd about the truss rod cover. Most of the other similar guitars I have seen pictured, the cover just says "Spirit", and nothing else. Mine says "Spirit", but underneath that it says "MADE BY GIBSON" in all caps for some reason. I have had to search pretty hard to find something similar, but I found a 1982 Spirit 1 (the single humbucker version) that has it, and a 1982 Gibson Spirit that has it as well. The headstock is rather redundant looking on the latter one. It says "Gibson" on the headstock, and "MADE BY GIBSON" on the same headstock. That is rather silly if you ask me.
So, the serial number is 834025539, which indicates it was manufactured at the Nashville facility, but everything I have read says that all Spirit guitars were made in Kalamazoo. I am wondering if maybe a few were made in Nashville, including mine, and that is why the cover looks a little different? If anybody know anything about this, please let me know.
