Hello, I am looking for new flatwounds for my bass. It already has flatwounds when I bought it but the low E snapped. They really played well and are very smooth. I now am looking for similar strings but they all seem to have a small winding overflow such as in the first picture. I try to find a very smooth string as shown in the second picture where the winding is almost not visible. Does anyone have any tips for such strings? Also, is it okay to just buy 1 low E sting or better a whole set when changing them?
