Lindsey Stirling uses a Luis and Cark violin from the early 1900s, Yamaha SV-250 Electric Violins. She recently released a signature violin she helped design. After her signature song, the violin is called Crystallize and was created with Yamaha. You can check it out here! Brett from Twoset uses a violin from 1952. Eddy uses an unlabelled violin repaired around 1917, although this may have changed recently. Brett also has a viola gifted to him by Eddy for his birthday, much to his amusement and slight disgust.
