Hi Guys,
My 2 cents worth of info on Wikinson Parts.
Wikinson nowadays oem their parts from various parts manufactuer like Japanese Gotoh and Korean Jin-ho. Basically the better wikinsons are made by Gotoh so essentially they are the same thing but the specs wikinsons.
As for the Korean Jin-ho, they are originally made in Korea but as the cost of production went up in korea and the demand for low-priced parts pile in. They had made the shift of some of their product lines to China.
Currently, I still can differentiate the Korean and Chinese parts but this is getting more and more difficult as the Chinese quality had improved vastly and in my own opinon the difference in price as well as quality will close up in the next 1-2 years. Gotoh is still one of the prime leaders in top notch value for money parts.
