Re: But how can it be,it`s MIK?
It doesn't really matter what country it is made in, it matters on the quality put into the construction.
However, there is a reasoning for MIJ generally being better than MIK. Many MIJ guitars are intended for sale on the Japanese market, if they weren't exported to other countries, they would still get made, so when companies bother importing/exporting MIJ guitars, they generally wouldn't bother with the lower quality brands.
Even if not one single MIK guitar was not sold in Korea, they would still get made. Companies are taking advantage of the lower production cost. Basically they are going for the cheapest decent product they can make in most cases, so quality is balanced with cost. It isn't necessarily a bad thing, that was what Fender went for as well.
