Pirastro Eudoxa Violin A String, Aluminum-Wound Gut, 4/4 - 14

Pirastro Eudoxa Violin A String

The Pirastro Eudoxa Violin A String combines an aluminum-wound sheep gut core with a ball end for 4/4 violins. Four gauges, 13 1/4, 13 1/2, 13 3/4, and 14 PM, provide different playing tensions. Lower numbers identify thinner strings with less tension; higher numbers indicate thicker strings with greater tension.

For violinists choosing a replacement gut A string, these options allow tension adjustments while retaining the same materials and attachment. Pirastro uses 13 3/4 PM in its medium set, making it a useful selection reference. Match an existing numeric gauge for a familiar setup, or choose a lower or higher option when adjusting your instrument's string load.

Pirastro manufactures the Eudoxa family in Germany and forms, winds, and polishes its sheep gut cores by hand. The series offers warmth and tonal variety for orchestral playing, chamber ensembles, and recording sessions. Every option shares the same full-size fit and ball-end connection. Black peg-end silk and white/violet tailpiece wrapping help identify the A position when installing a replacement or organizing spare strings.
