Thunderblack 46-53 CM / 18-21 “

24.00 + VAT

Thunderblack is a set made with three different types of synthetic elastomer. In the third and fourth strings, the density of the elastomeric material is also increased by adding micronized metal iron powder during the extrusion phase.

This technological solution allows for the same working tension to have smaller diameters, greater volume and sustain than any type of polyurethane and silicone rubber strings available on the market. The Thunderblacks ensure fast and stable intonation. Thanks to the metal powder there is also a great slipperiness of the fingers.

How to install the G string

These strings are made with an elastomer. An elastomer behaves exactly like a rubber band: it stretches a lot under tension.

At the same time, being a rubber material, it doesn’t slide on the nut (and that’s precisely why rubber is used in shoe soles): when tuning, you should keep it out of the nut groove and only reinsert it at the end of the procedure.

Below, we present two different procedures explaining how to install the E string (but these procedures also apply to the other three strings A, D, and G).

Once installed, the strings should be pulled several times by hand (as seen in the video): this way, pitch stability is achieved within a few minutes.
