Not at all but not because they aren't consistent. IME Gibson manufacturing in general is to a different standard than practically all the rest . Gibson simply does things in the way they always did without caring if the precision that others routinely manage is just missing. Who else doesn't even buff the finish up to the fingerboard edge or on the back of the head ? leave razor scrapes in every bound fingerboard, A lip in the binding. These are not QC just bad process. All that said they are consistently good sounding and perform well, I can't remember when I last saw a poorly functioning truss rod. People just expect Gibson to be Gibson and accept things that they would reject on anything else at the same price.
