The Aquila 45U - New Nylgut Series, Ukulele Single String - Concert, Madolin Tuning, G (3rd), Wound is crafted for concert ukuleles in CGDA (mandolin/fifths) tuning. This model’s silvered copper wound G string uses a New Nylgut synthetic core, so players get a tone close to gut strings with the benefit of modern tuning stability and longer life. Manufactured in Italy, the 45U gives musicians an easy way to try alternative tunings on their concert ukulele. The single string provides a practical option for those wanting a mandolin-style sound.

What sets this model apart?

While standard strings lack the same tonal qualities, the YRS-23 features a wound G string made from silvered copper over a New Nylgut core, creating a defined, singing sound. The brief stretching period allows for rapid tuning stability post-installation.
