Far I can tell, yo, Gibson has always had QC issues, and regardless of whether a guitar was shipped to Europe or the Americas, it was a bit of a cr@pshoot.
The exception was Japan, and that was because Gibson's (former) exclusive distributor demanded and paid handsomely for the right to select the guitars to be sold in Japan. In addition, there were numerous "Japan-only" models and parts.
As such, a guitar with proven Japanese provenance commands a premium in the marketplace.
Since Gibson terminated the distribution agreements with both Yamano and now Rosetti, I suspect that these moves were motivated by a desire to cut out the middleman and not QC. Also, Gibson has stated that it sees high volume instrument retailers as the future and not smaller independent sellers.
