LimaGuy said:That is correct. Does it have a ser# on the control cavity?
Or on the headstock?
The earliest models didnt have a ser# at all.
Most of them had a ser# on the control cavity that started with NS.
The very late models had a ser# on the headstock and were made at a different factory in Korea.
Post a photo so we can see and confirm![]()
I concur with LimaGuy.

W Tee Eff?
