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. Scaled to fit 3/4 size bass with a playing length of 41 3/4 inches (1060mm), light tension strings will allow for easier bow response. The HH615 Low-C (extended E) string is only available as a single string and is not part of the HH610 set.
