In a Mental Floss article, Henri Grissino-Mayer, a UT geography professor, and Georgina Deweese from the University of West Georgia, worked together to analyze and date the wood in a bass. The instrument which had been played for more than 40 years, was assumed to have been made in the 1800’s. However, Grissino-Mayer and Deweese were able to discern a 317-year age sequence in the wood, with rings dating from 1445 to 1761. This indicated that the tree was harvested sometime after 1770.
They also suggested that the spruce tree from which the bass was made came from an alpine area of western Austria, and crafted by a French maker in the late 18th century.
