IF you have EMG pickups, they had a dating scheme in the 80’s and 90’s that was very easy to use. And it may help you in tracking down just when your guitar, or at least the pickups were made.
It’s alpha code for the year of manufacture.
So, for instance one of my guitars, my Standard Pro 0202, has IA, which is 1991 – seen below
For example IE is 1995
IB – 1992, etc
They quit doing that I believe in ~2000 and since put dates like 1/12/07 – I asked EMG directly when I ordered a set from them (thru a dealer but I called them to give specs)
Hopefully this may help in figuring out what year your guitar was made, or at least the pickups. And obviously anything without alpha codes is a way later model, not an Original Pre/Samick, Pre/Gibson, or it could be an original with “updated” pickups.
