Welcome to forum land. The serial number indicates the guitar was built in 2009. But something is amiss if it's been hangin on the shop wall for four years[?][?] I would not worry to much re: country of origin. Quality differences are minimal, if any at all. Washburn has been a bit inconsistant re: the Buzz Feiten system. For what it's worth I would not worry one way or the other, particularly with a 12'er.
So, if the price is right and given how long it's been hanging I'm guessing a deal is possible and you clearly like the guitar.... Go for it.
Pics when/if you buy are always welcome.
If you are interested, and still looking at this thread, this came up on the local Cl.http://tampa.craigslist.org/pnl/msg/2699112485.html
