Aquila 91U Thunder Reds Bass Ukulele Strings 4 String 18-21" Scale

BASS UKULELE AND ASHBORY THUNDER REDS® SETS

The Thunder Reds® sets: a unique look and a strong, consistent sound.

Until now, it was necessary to increase a string’s gauge to reach lower frequencies. But increasing the string’s diameter also increases internal dampening. That makes the string less bright, less responsive and more muffled:

the thicker the string, the duller the sound.

Our revolutionary new approach —never introduced before us— changes the specific weight of the material, increasing it progressively to leave the gauge unchanged.

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