I'm new here and new to Washburns, but not new to guitars. This post should tide you over until a more knowledgeable poster comes along.
They've been making them in Asian country's since at least the late 70's, starting in Japan. What model is yours? It is a 92. If Washburn is anything like the other guitar companies, the best stuff is made in USA, followed by Japan, then Korea, then Taiwan, then China. Although in recent years, there is little difference in quality regarding the country of origin--the wood doesn't care where the CNC machine is.
