Yamaha’s NTX models (NTX1, NTX3 and NTX5) were designed to make it easy for electric and steel-string acoustic guitar players to add the warmth and beauty of nylon-string sounds to their tonal palettes. NTX guitars have slimmer bodies, shallower neck profiles, and narrower fingerboards than classical guitars, providing a more familiar playing experience. The NCX models (NCX1, NCX3 and NCX5) have classical-style neck profiles and fingerboards.
