So, there is nothing about your instrument that would put it in the late 60’s-early 70’s time frame. I think the 1980 date is correct. This is useful information to me since I was unaware the 80’s Kays were first produced in Taiwan rather than Korea. Thanks 😉

Even a reputable dealer can have a salesman that is either ignorant or anxious to tell a buyer what they want to hear in order to sell a guitar.[/quote]

A little late to the discussion 🙂 One of these 2 pickup SG style Kays has come up for sale locally with a claimed date of 1969. During some research I found this interesting thread and did begin to wonder about the advertisers claim.

However, it appears that Kay were indeed producing these guitars in the 60s according to this guitar undergoing modifications – both neck and body are stamped 17.7.1969.

The value of these guitars seem to be around £50 – £100 in the UK.
