You can make your ukulele sound even better with the much-talked-about new Aquila Red Series Soprano Ukulele strings. This is because these strings are of unprecedented quality. Aquila was already known for its good quality strings. But with the Red series, they bring a whole new idea to the market. These strings are filled with red copper. Which ensures that the strings do not differ much in thickness from one another. This not only makes it more pleasant to play, but also makes the sound more balanced and beautiful in tone.
