Aquila Bass Ukulele Flat Spirals 4 Strings – E’A’D’G – 4 strings 18-21″ / 46-53 cm scale

These strings are truly innovative for at least two reasons. Firstly, they do not use metals like steel or nickel, that are stiff, but instead they use pure copperthat is softer and has higher density and result in richer acoustic performance. In fact higher the density, better the sound. Secondly, 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.
