Pretty sure Gibson manufactures guitars in Nashville and Memphis (semi-hollow and custom shop), TN, as well as Boseman, MT (acoustics maybe). I think they also have some manufacturing in Canada.
I've heard they are being made at the old Kramer factory in NJ.
The best ones are still made in Kalamazoo.
Gibson makes their semi-hollows and hollows in Memphis. Les Pauls are made in Nashville.
