The New Nylgut Series of ukulele strings by Aquila were developed by blending three different synthetic components to make a composite material that sounds better and stays in tune better than standard nylon strings, but with the feel and playability of genuine gut. An added feature of this exclusive composite material is that is was designed to absorb less moisture than other strings; which greatly improves intonation and tuning accuracy. The New Nylgut Ukulele strings have a density similar to gut, but provide an even more refined sound; eliminating the characteristic metallic-like tones often found in other synthetic designs. For the best sounding synthetic gut string for ukuleles, that still gives the player the feel of genuine gut, Aquila New Nylgut are the perfect choice!
