Founded in 1958 by James How as a small, UK based, family-owned and operated company, Rotosound core values are little changed today. More sophisticated machines, designed and built by the late founders son, Jason How, still produce high quality instrument strings using only the best materials and a great team of people who really love what they do. Each string is physically and visually inspected at every stage of the manufacturing process to get maximum consistency, ensuring each one is unrivalled in tone, tuning stability and durability.
