The sound is developing and increasing in power and quality. It´s a supremely appealing violin and I´m proud to have it in the collection, and to use it everyday." Mario Tubert. We delivered this violin in person to the distinguished collector Mario Tubert in Argentina. As we had only had email contact with Mario during the making process, we benefited greatly from Jonathan Sparey's expert help in adjusting the tonal response and playability.
