According to Dan Erlewine--a guitar maintenance expert--who knows more than several of us combined, says that Gibson Acoustics made since they opened their Montana factory are equal to, and possibly better than the Gibson acoustics made in their heyday before the early 60's. He places these on par with Martins, as well. They have different tonal qualities, but both are excellent guitars--pricey--yes, but excellent guitars. (It's the mid 60's to pre Montanas where you need to be more careful. But even there I wouldn't discount finding good ones--but in general the Montana ones will be better.
