I currently own guitars made in (in rough region order):
- United States
- Canada
- Finland
- Poland
- Slovenia
- Japan
- South Korea
- Indonesia
- China
All of these guitars are good. So the country of manufacture or factory doesn't matter to me much, the quality of the guitar does.
For example my only acoustic is a Chinese made, all solid wood Ibanez AW800 because I liked how that guitar played, sounded and felt better than the Martins, Yamahas and others I played when shopping for one. 17 years later it's still great.
Out of these countries, Indonesian made guitars have been the most impressive to me for price vs quality. The Ibanez BTB33 bass and the Schecter Coupe hollowbody I have are nearly flawlessly built, certainly well above their price tags.
I think it is interesting to know which factory made which guitar, but especially for older guitars it's difficult to find out. But it makes no difference to me in enjoyment of the individual guitar.
With Strandberg, to me the issue is not the country of manufacture, but the quality vs price. It feels like those Asian labor savings are not translated to the buyer price. I've played Japanese made Strandbergs that sold for about 3000-4000€ some years ago, and those were really nicely made and totally worth the money, but expensive to import.
On the flip side, the 2400€ Korean made Strandberg Boden I briefly owned was literally the worst quality guitar I have ever owned. Unusably bad fretwork, chunk of wood missing near the nut, worst quilt top I've ever seen, finish flaking off the hw right from the start and more. It was a disgrace they tried to sell it at all - but somehow that guitar made it from the Korean factory all the way to Sweden and then to Finland only for me to have to discover it's a bag of shit and return it. I put Strandberg on my "do not buy list" because of that.
