Aquila 137C - Zaffiro Series, Classical Guitar String Set - Superior Tension delivers eco-friendly brilliance

This model is built for players who demand both a modern sound and a sustainable approach. By using "Nylonplant" for its treble strings—a unique plant-based nylon developed to reduce carbon emissions during production—the set stands out. Players experience a bright, prompt response reminiscent of fluorocarbon strings and benefit from faster, more stable tuning. Choosing this set means supporting an environmentally conscious design for those who care about sound quality and the planet.

Standout features for the eco-minded guitarist

What sets the Zaffiro Series apart is its use of Nylonplant material, which reduces CO2 emissions by more than half compared to standard string production. For the basses, silver-plated copper windings are wrapped around a multifilament Supernylgut core. This construction provides power and tuning stability that are uncommon at this price point.
