The Banjo 2nd String is treble gut with a gauge of .76mm.
Plain gut strings are available with a natural or varnish finish. Natural strings are hand-rubbed with a light oil. Varnished strings have three coats of finish before being hand polished with the oil. There is an additional charge for varnished strings.
Gamut Music is pleased to offer natural gut banjo strings with the same type of twist and gauge as those used in the late 19th century. The banjo first and second strings are made from our finest beef serosa treble gut (120cm, 48" in length). The third string is a single twist Lyon-style gut, and the fourth is treble gut wound with silver-plated copper wire (120cm, 48"). The shorter fifth banjo string is made of treble gut (80cm, 30").
Banjos were very popular in the United States in the late 1800s, and consequently there are lots of strings that survive for us to measure and replicate. From the ones in the Gamut Academie String Archive, it is evident that violin strings were repurposed and relabeled as banjo strings for the first, second, third, and fifth positions, with a guitar fourth string used for the banjo fourth.
