 Torres used a string scale-length of 650 mm, which is usually the standard length for today's modern classical guitars.The designs Torres developed were later adapted by several very influential luthiers; Manuel
Ramirez (1864–1916) and his brother José Ramírez (1858–1923), Hermann Hauser, Sr. (1882–1952) and Ignacio Fleta (1897–1977).Today, luthiers use the ideas and designs of Torres, Hauser, and Fleta in their own guitars.
