Mandolin that used steel or steel-and-bronze strings. Pasquale Vinaccia (1806–c. 1882), modernized the mandolin, adding features, creating the "Neapolitan" mandolin c. 1835. Pasquale remodeled, raised and extended the fingerboard to 17 frets, introduced stronger wire strings made of high-tension steel and substituted a machine head for the friction tuning pegs, then standard. The new wire strings required that he strengthen the mandolin's body, and he deepened the mandolin's bowl, giving the tonal quality more resonance. He didn't introduce the bent soundboard, as it was present in some of the instruments made by the previous generation for bronze strings. Other luthiers who
