Aquila Silver Rumbler U-Bass Strings
Using Aquila's patented technology and formulas, these strings are engineered specifically for the Kala U-BASS. Their special Nylgut compound includes calcium carbonate to give them increased density, stability and the ability to resonate tone at very low frequencies. They have pure bass, clear tone and a low end that lives up to the name.
