And then?... How about the era of Chinese acoustics?
Ah -- that's for someone else to write!
Being mostly a "solid-body electric" fan, the acoustic stuff is a little bleary for me. Someone once said the acoustics went something like "Japan to US to Korea," but don't quote that as the source eludes me. Certainly, the first Washburn triumphs in electrics were the MIJ, then production shifted to Korea, then hived to Indonesia & Red China.
As mentioned in another thread, production for some semihollows like the HB35 was literally moved from Japan to Korea by Samick. In recent years, Samick has focused on the huge Indonesia facility they opened in 1998 -- in fact, I think Washburn has some models with an "SI-" prefix.
As a minor fan of the evolution of the Squier brand, it's clear that there are "teething pain" issues when moving production into a new region.
Early Mexico Fenders are often terrible; nowadays, they're pretty much on par with the more expensive "USA" models (built a mere three-hour drive north, actually).
Ten years ago, I sneered at Korean guitars, & today I'm usually impressed.
Aside from Samick, I'm yet to be won over by Indonesian manufacture.
Guitars made in India or Vietnam seem to suffer when shipped to the dryer/cooler United States, causing any number of problems wih finish, glue, splitting, warp/curl, &c.
Instruments from the PRC are (to put it mildly) a mixed bag, like Japan in the early '70s, where a factory is turning out jaw-dropping axes for cheap, & another next door creates absolute trash for the same price-point.
