Gurians are kind of legendary here in the U.S., at least they were where I came from. I played a jumbo at The Guitar Shop in D.C. back in the '70's and it was a winner. Michael Millard of Froggy Bottom Guitars came out of the Gurian shop and he now makes some of the best steel strings on the planet. I'm fortunate to own one of his F models.
Last year I acquired a Canadian-made 000 12 fret Boucher with an Adirondack top and it's the best fingerstyle guitar I've owned and it also works well for Old Time flatpicking.
