This is an extra heavy single length gut core string with a and a thin silk layer wound onto the core between the gut and wire. Because the wire is a solid metal, the wire is polished slightly to reduce the feel the texture the wire. It is intended for use on a standard length, (1.05cm) contra bass string length which needs to be tuned lower than the standard E-4. The weight of this string will allow the strings to be tuned down to C or D below the standard bass E-4. The tone is quick and bright. The end of the string that goes into the tailpiece is knotted with a loop of gut on the end.
Wound strings for the contra bass are warranted for a period of six months from the date of shipping.
