So, I had a scratchy pot on my 1993 Korean Epiphone, so I decided to swap out all the parts just for a change since I have had this guitar since 1995, and also to practice rewiring a semi hollowbody. So, I got the guitar out and started looking at the fret nibs. I decided to do a little research just to see when Epiphone stopped doing to fret nibs of the Sheratons. This is when things started getting interesting. (By the way.....they stopped doing the fret nibs after 1995). When I was living in Las Vegas, I had originally taken this guitar, along with a lot of my others to Ed Roman guitars to get an estimate on their value for insurance purposes. They had told me that from the serial number they had dated the Sheraton II back to 1991 Korea. Well, I started looking at photos of early 90's Korean Sheratons while researching the fret nib thing, and noticed that mine looked very different. Here is a photo of a known early 90's Korean Sheraton headstock: Mine: Known Korean bridge: My Bridge: Also, I had this label inside the f-hole which after some research I find out that this is the pattern on the labels that Epiphone put in their Japanese acoustics in the early 80's. But the problem was the serial number: This number dates the guitar to October of 1993, made in the Korean Samick factory. Obviously this is what that guy at Ed Roman used to estimate the value of this guitar. So, I put all of this info on the "Epiphone Owners Group" page on Facebook, and got a lot of responses. Turns out that yes, this could have been a Samick number, and that Samick may have just made the guitar with leftover Japanese parts at the time. But, there was the issue of the middle Japanese label and the completely different logo on the headstock. As more people chimed in, it turns out that the 80's Japanese Sheratons used a very random serial number system that really did not have any real order, and that Samick actually repeated some of the same numbers in the 90's. Very interesting. Also, the font is different. The consensus is that this is indeed a Japanese Sheraton, and one collector said that from the headstock, it is likely from around 1983. So, I had to do one more thing for confirmation. Something I really have had no need to ever do because I always thought the pickups sounded good. I pulled a pickup and saw this. From the pickup, it looks like this guitar was likely made in the Matsumoku factory. This is a later (80's) Maxon pickup from what I understand. Pretty cool finding out that a guitar your have had all this time and believed it to be Korean is actually a pre-Elitist Japanese made guitar. It pretty much doubles the value too, but I would never sell it because it has always been one of the best built and playing guitars I have ever owned.
