A brilliant collaboration between two of the best in the business, Julian Lage and Collings Guitars.  Having watched the development of this guitar over the course of several years we can say without doubt it was done right.  Julian did not settle on the first guitar they handed him and Bill of course did not except anything less than perfection.  The result is the closest thing to an old Martin guitar in a new instrument we have heard.  Collings has a nice write up of the project here.  We order these the same way Julian plays them.  Adirondack top and the 1 11/16" nut width.
