Scaled to fit 4/4 size cello with a playing length of 27 1/2 inches (700mm), these electric cello D strings will fit a majority of standard sized electric cellos. 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 and low F are available as single strings.
