National ResoPhonic Style N 14 Fret German Silver The National ResoPhonic Style N is the same guitar as the Style O, without the etched Hawaiian scene. This particular model is built with German Silver. This material, used for the body and coverplate, is the same alloy used by the Dopyera Brothers to create the first National Tricone guitars in the late 1920's. German Silver produces a bit more clarity and focus than the bell-like brass bodies. The tone is a bit mellower and more controlled, with a bit less reverberation and overtones and a more extended low end. The National Style N-14 Fret reproduction meets the demands of players needing easier access to the higher frets.
