Helicore Pizzicato bass strings are multi-stranded steel core strings that produce a brighter tone quality. The core design makes for strings that are very easy to play under the left hand. Damping is reduced to create maximum sustain and "growl". Scaled to fit 3/4 size bass with a playing length of 41 3/4 inches (1060mm), medium tension strings are optimized for a majority of players. The HP615 Low-C (extended E) string is only available as a single string and is not part of the HP610 set.
