On this type of strings, there have been a few reports of the following problems:

  1. episodes of breakages on gauges 36-46 NNG
  2. NNG chanterelles (36-46 NNG) have less ‘silvering’ sounds compared to those made with gut
  3. the thicker NNG strings have more sound in itself as compared to those in gut, but they can’t substitute the wound strings on certain positions (5th course in Reinessance Lutes, lower octaves, 6th and 7th of theorbos of big dimensions)

In order to successfully resolve the above-mentioned issues 1 and 2, instead of using pure Nylgut, we introduced a new blend of Nylgut with a low percentage of our Sugar polymer, that produces a sound closer to gut, providing at the same time an increase in the strength of the string.

In gauges greater than 79 NNG instead – see above point 3 – the Nylgut has been replaced with our bioplastic called Sugar, that has the same specific weight and color of Nylgut. Thanks to this replacement, the sound has greatly improved, becoming comparable with aluminium wound strings. This improvement has been extended up to the 112 NNG.

It should be noted that Sugar allows better acoustic performances also compared to the CD strings, in gauges from 75 CD to 110 CD.

Comparative tests showed that CD strings, even if they are made with Nylgut loaded with metals, have a rounder sound compared to an NNG with equivalent gauge.
