A fundamental aim 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 climatic). The New Nylgut® has precisely these qualities: allowing 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.
