Teisco are were Japanese. Meng is from Singapore. What suggests they'll be made in China?
Yeah, I always thought all the Teisco stuff was made in Japan. Kawai owned them for a while, and although some of their products (I think) might have been made in Korea, the Teisco stuff was always made in Japan.
Manufacturing
electronic products in China makes sense, as there's loads of companies there with the technology & facilities to mass produce them at a very low cost.
For acoustic instruments though, probably not so much unless you're selling a re-badged copy of something a company is already manufacturing.
