Sized to fit long-scale viola (body length 16-16 1/2 inches) with a playing length of 15 inches (380mm), these electric viola A strings will fit a majority of standard sized electric violas. They will also work well on acoustic instruments, providing a clear, focused tone while still allowing for tonal subtlety and expressiveness. Designed in partnership with Ned Steinberger and NS Design, the D'Addario NS Electric Strings can be used on electric instruments to bring out the best in them. Each string is designed to enhance the expressive range of tone sought after by the most discerning players. The set consists of regular tuning strings (A, D, G, C). Additional high E is available as a single string.
