The New Nylgut® is the first product developed and patented by Aquila. The New Nylgut® is nor common Nylon or Carbon (Fluocarbon fishing line or PVDF), or a mix of them. It is a plastic compound of three different components Compared to Nylon, the New Nylgut® produces a better sound and stays in tune better, this because the moisture absorption is less of .1 against the 2.0 of Nylon normally employed for the musical strings (i.e. Du Pont Tynex® polyammide 6-12). Due to the higher density, similar to that of pure gut (1.30 gr/cm3), the New Nylgut® produces a better sound than Nylon and it is not so metallic like those of the so- called ‘Carbon’ (Fluorocarbon) PVDF strings. In other words, it is probably the first genuine syntetic gut in the world.
The best sound quality develops when the strings have completely set, which may ordinarily take sometime. To achieve a stable intonation in just a few minutes you can repeatedly pinch each string at midlength with your fingers, pull it decidedly sideways and tune it up again. Stop when the string does not pull out of tune anymore.
