Until the mid-20th century Ukuleles were mounted exclusively in gut, a material that had been used for thousand of years and that combines excellent promptness of attack with brilliance of timbre - very different, in other words, from modern nylon strings. And until recently the typical sound quality of gut has been a constant point of reference for luthiers, composers and performers alike.

A fundamental aim of Aquila's research has therefore been to make a new synthetic product having the same acoustic properties as gut - but without its typical defects - (high cost, limited duration and high instability under varying climatic). Nylgut® has precisely these qualities: allowing one, on the one hand, to rediscover the sonorities familiar to the great 19th and 20th century Uke masters; and guaranteeing, on the other, a stability of tuning higher even than that of the best gut and nylon strings.

The tone is bright and snappy and Aquila strings are by far the most popular strings among ukulele players. For those who find theses strings too bright, we recommend Worth strings. 

Concert strings are sometimes also used for soprano ukes because they are a bit fatter and give a slightly fatter tone as well.
