A fundamental aim of Aquila's research has 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 climates). The New Nylgut® has precisely these qualities allowing one to rediscover the sonorities familiar to the great 19th and 20th century Uke masters and guaranteeing a stability of tuning higher even than that of the best gut and nylon strings.

Notice!

Just like gut, the New Nylgut® is liable to suffer from cutting edges. Before stringing the instrument, make sure the nut and bridge are free from sharp edges and the nut grooves are not too deep and perfectly smooth. 
You can get rid of sharp edges with very fine grit sandpaper or the finest steel wool.

The best sound quality develops when the strings have completely set, which may take sometime. To achieve a stable intonation in just a few minutes, you can repeatedly pinch each string at mid length with your fingers, pull it sideways, and tune it up again. Stop when the string does not pull out of tune anymore.
