Scaled to fit 3/4 size bass with a playing length of 41 3/4 inches (1060mm), heavy tension strings will allow for greater projection and volume potential. This D string is nickel wound. Helicore Hybrid bass strings are multi-stranded steel core strings that produce a moderately warm tone quality. The core design makes for strings that are very easy to play under the left hand. Damping is optimized to create a good balance between pizzicato sustain and bow response, allowing for good performance across many playing styles, from symphonic to jazz or bluegrass.
