Behold the basic model Martin ukulele – one of the most standard of ukes – and yet extremely classy and professional in all of the ways that matter. It has a solid mahogany top, back, sides, neck, including the front of the headstock. Features include a Brazilian rosewood fingerboard (displaying some exceptionally pretty grain) and Brazilian bridge; having four “machine” tuners (also called “patent pegs”) that have metal clad shafts (not to brag or anything) and black buttons that could be wood, or Bakelite or plastic (celluloid).
