They probably did. At that price range, I wouldn't be surprised if it's WMI or Fujigen, or someone reputable building it, but they just decided the "Boss" name would be more suitable.
I honestly don't doubt it plays great and is well-built. But they really skimped on the design, honestly. Especially that headstock. I'm not even being facetious. When I first saw it, the looks made me think Fesley or Donner or one of those Amazon brands.
I get it. It is a pretty pedestrian design. Maybe have a MIM Strat or Tele to put the guts into...or an Epi LP.
