Super SensitiveRed Label Series Viola D String 13 in., Medium
Independent shopping perspective
The Korena take
Sized for a 13-inch viola, the Red Label Series D is a medium-gauge string with a solid steel core and nickel winding. It is made with student players in mind, combining a quick, responsive feel with a bright, powerful voice. The string is designed to remain stable when temperature and humidity change, which helps keep setup more consistent as the instrument moves through lessons, school use, and home practice. A removable ball end gives the D string its specified end configuration.
