Martins premium classical strings are tonally superior to nylon. The proprietary synthetic material emulates gut strings that have been around for centuries. Magnifico strings, developed exclusively with Aquila, offer precise intonation and exceptional tuning stability. All Nazareth-made nylon guitars and custom produced nylon guitars are strung with Martins Magnifico premium classical strings. Unlike Martins standard classical strings, which have a ball-end, Magnifico classical strings will be offered only with the traditional tie-end.
