Guadagnini moved three times his studio, to Milan in 1749 and much later to Parma and Turin. He had improved most of his know-how during his first phase in Piacenza, with slightly widened violins, sharp angles in the sides and his much effective reddish-brown varnish. Guadagnini's violins have a strong and harmonious sound and are the best concert instruments from the mid-eighteenth century.
His violins from the beginning of his Milanese period are already demonstrating his great maturity. One of them named the Berkova, made in 1755, was sold for $ 720K including premium by Tarisio on May 2, 2013 although the original coating was not complete.
Tarisio sells in New York one of the best violins made by Guadagnini in Milan, dated 1753. Despite a frequent use in concert, the instrument which has been carefully maintained is in an excellent condition. It is estimated $ 1M in the online sale which ends on October 13, lot 254. Its brilliant sound is demonstrated in a YouTube audio by Tarisio. Here is the link to the auction house's website.
