After weeks of searching, researching and trying out a bunch of acoustic brands, I have finally found what I was looking for. The Cordoba C5 is a full sized acoustic guitar with a warm, rich and deep tone. My Cordoba has no 'buzzing' at all. When I had to make a decision in choosing an acoustic, it not only had to look nice and produce this warm deep sound but my acoustic should have a truss rod as well.
