OM1
A steel string guitar built on the tradition of the most beatiful Martin instruments. The classical pre-war scalloped X bracing with double transverse tone bars gives to this instrument its typical sound, with a powerful bottom end, projecting midrange and plenty of harmonics. A balanced and enjoyable instrument, a necessary tribute to the history of the acoustic guitar.
