GHS Contact Core are designed with an extra-thin segment near the ball end. This thin segment rests on the bass saddle and brings the central core of the string into very close contact with the saddle, providing a brighter tone than a conventional string of the same gauge. When tuned to pitch these strings have slightly more tension than conventional strings, a crucial feature for the low B string in a 5 or 6 string set.
Bass players looking for piano-like clarity in their basslines and chords will love these strings. The contact core design allows better contact with the bridge, increasing sustain and definition.
