It all began a few years ago with the EU and a thing called the Ro HS (Regulation of Hazardous Materials) and Gotoh in Japan basically changed their production to ensure they didn’t lose the European market, and that being manufacturers who shipped to Europe, which is most everyone.They changed pretty much everything for the “export” market, and export to most makers means anything but US. They have a way of producing black again now so expect it to all go back to the way most of us prefer over of old esp's does not have any serial on the back of the headstock.
