Flatwounds on my Kala U-bass
As much as I liked the original "rubber" strings that come with the U-bass.... the addition of the Flatwounds have made the U-bass even better. With the flatwounds you can get a much more percussive sound when you want but can also be played softly for a warm softer sound. I run my U-bass through a Fender Rumble 40 and it sounds wonderful. I can get a real sounding electric bass sound to the woody sound of a dog-house. Thanks for a great product.
