DAddario J610 Prelude Bass 1/4 Scale String Set Prelude bass strings are multi-stranded steel core strings that produce a warm tone quality with good bow response. The special core design and reduced tension makes for strings that are very easy to play, especially for younger, developing players. Ideal for use in educational environments, Prelude bass strings maintain a clear, warm sound that blends well across the ensemble. The 1/4 scale strings are gauged specifically for 1/4 size bass with a playing length of 35 1/2 inches (900mm).
