Can someone please give me some information about the La Bella Black Nylon Tape Wound strings for upright acoustic bass? I haven't a clue on what is now on my bass. They were on it when I purchased the bass. I am not particularly happy with the sound of these strings. I play in a jazz quintet, and we play all the jazz standards, and I am not getting the sound that I prefer from these strings. I am not getting a good clean sound, specifically on the low end. I have been studying about different types of strings and the La Bellas caught my eye.
