Carlo Giuseppe Testore

Carlo Giuseppe Testore (c. 1665–1738) was an Italian luthier, who worked in his later life in Milan.

[1] Carlo Giuseppe Testore is especially valued for his double basses.

Currently, Russian violist Yuri Bashmet plays a Paolo Antonio Testore instrument.

National Arts Centre Orchestra's former principal cellist Amanda Forsyth uses a Testore cello, manufactured in 1699, as does solo cellist Jacob Shaw with a cello of unknown date, belonging to the Royal Danish Academy of Music collection.

Clifford Spohr, principal emeritus of the Dallas Symphony Orchestra double bass section, currently owns and uses a double bass made by Carlo Giuseppe Testore; this instrument was built in Milan in the year of the maker's death; it has five strings, plus a low C extension by Winterhalter, giving it a range greater than normal.
