Product Information

These strings are truly innovative for at least two reasons. First, they do not use metals like steel or nickel that are stiff, but instead they use copper that is softer and has higher density and result in richer acoustic performance. In fact, the higher the density, the better the sound. Second, these strings feature a bioplastic monofilament core called 'Sugar', which is exclusively produced by Aquila on a global scale. Sugar has been proven to have superior acoustic performance compared to other plastic materials, as evidenced by laboratory measurements. Only compatible with 4-string Acoustic-Electric Kala U-BASS.
