Most guitarists associate Martin with steel-string guitars like its popular dreadnought and OM models. However, the company has been building guitars since 1833, and steel strings only became common in the early 1900s. Before that, guitars were strung with gut strings. Martin began offering a “classical” model in the mid-1930s based on its 00 size and has offered classical models ever since. In the 1990s, Martin even collaborated with the late Thomas Humphrey on a model based on his Millennium design.
The 000C Nylon we received for review has several unusual features, including an extralong 670-mm (26.44- inch) scale—even longer than the 665-mm scale on some classicals—and a fingerboard and bridge made of Richlite, an eco-friendly product made from recycled paper and resin that looks and feels like black ebony. Internally, the 000C Nylon uses an A-frame variation on Martin’s traditional X-bracing pattern. The A-frame bracing supports the fingerboard extension in the upper bout, while a version of standard X-bracing graces the lower bout. This makes the 000C Nylon the only guitar in this review that is not fan braced.
