We really love these new strings from Aquila for restringing a uke or classical. These are made in Italy of a trademark material called Nylgut. Aquila says that Nylgut sounds like actual traditional gut, but doesn't suffer from instability due to temperature and humidity like gut. The basses on the classical set are traditional silver wound. In our opinion they have a great, lively, bright sound, and a higher tension than nylon, especially nice if you are already used to steel strings and move to classical. The high tension also attributes to the projection of these strings. Restring a uke with these and it nearly jumps out of your hand! Stop by and grab a set today!
