Aquila ThunderReds 4-String Bass Uke String Set (18 - 21" Scale)

ThunderReds Series

Recommended Retail Price


ThunderReds 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 copper 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 ThunderReds ensure fast and stable intonation. Thanks to the metallic powder there is also a great slipperiness of the fingers on the strings.
