Martin?s 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 Martin?s Magnifico? premium classical strings. Unlike Martin?s standard classical strings, which have a ball-end, Magnifico? classical strings will be offered only with the traditional tie-end.
