The sheep gut core of the Eudoxa strings is manufactured, wound and polished in the traditional way, by hand. These stings have a well-balanced warm tone with a great diversity of sound. The low string tension results in a comfortable left hand feeling and make Eudoxa strings ideal for orchestra, chamber music and studio takes. The aluminum-wound, medium gauge A string is 13 3/4PM. Eudoxa A, D and G strings are manufactured in up to five gauges in steps of 1/4 PM. Please make a note at checkout or call us if you want a heavier or lighter gauge. These gut-core strings are stored and sold straight with no envelope.
