This illustration of a violin by J.B. Guadagnini was published in The Strad, September 1937. The following text is extracted from the article accompanying the photographs:
This is an interesting example of the work of Joannes Baptista Guadagnini dating from his Turin period, and made towards the end of his long and productive career. The maker worked at a number of towns in Northern Italy – in Turin and Parma, Piacenza, Cremona and Milan. The general model of his instruments follow that of Stradivarius, who although not his actual master, was the example both Joannes Baptista and his father Lorenzo followed throughout their working career.
Count Cozio di Salabue, who was his friend and patron, acquainted him with details of Antonio’s methods of construction, and possibly the recipe for his varnish, which the Count obtained from Paolo, Antonio’s son.
It is of historic interest to note that it is with this maker, who died towards the close of the 18th century, that we find for the last time the true Cremonese varnish.
J.B. Guadagnini’s violins are invariably constructed of excellent material. Moreover the maker left plenty of wood in his plates, and also adopted a medium model, which has subsequently been proved to be the best for tone.
