The Gold Tone OM-800+ Octave Mandolin (Mahogany) is tuned one octave lower than a standard mandolin. Octave mandolins are becoming increasingly popular as the main alternative instrument for mandolinists. The Gold Tone OM-800+ Octave Mandolin (Mahogany) includes a longer 22 1/2” scale (commonly used by private makers in Ireland) and an arched top, which makes it structurally stronger. It also has a compound radiused fingerboard preferred by many for playing speedy licks. Of utmost importance on any octave mandolin is the complicated setup required for low action without buzz. Gold Tone’s luthiers have perfected this procedure. Includes a hardshell case to keep this beauty in good shape for years to come.
