Thanks for the info.
I guess that the Koreans, unlike the Japanese, didn't go much on keeping records which is sad for 'Anoraks' like me.
The saving grace is that it plays so well.
The pickups may be a bit down on output (certainly compared to the 'S' serial one I have ,which I know is 1988/9), but the necks are just like glass to play-super slim and fast.
Cheers
