C.F.Martin has been upgrading a lot of its standard models in the last couple of years, and while the "reimagined" Style 18 and Style 28 models get all the press some lower priced Martin styles have been tweaked as well. Style 15 is a great example, as they're lighter in weight and better-sounding, with some nice vintage touches like diamonds & squares neck inlays and open-back tuners. Construction is with solid genuine mahogany throughout (no sapele) with both a more appropriate vintage color and satin finish than previous versions.
