Corelli Orchestra type 370 double bass strings are made of steel core wrapped with Nickel (G) and Tungsten/Tungsten (D/A/E). As an option, a C and B5 string is also available with tungsten winding. The string set is easy to play with a fast response and very stable in tuning. In addition, relatively little pressure needs to be applied when vibrating, whereby the powerful sound is preserved, all with a rich palette of overtones. Available in the Medium, Strong and Extra Strong version.
