Can you identify my bass strings? The strings that are on my Kay M1 (1950) are OK but what are they? Of course they are flat wound. Smooth felling to the fingers. The silk is different colors on each string. E-med. blue, A-Dark Blue or Black, D-violet or purple & G-white or as it appears dirty white. They were on the bass when I bought it several years ago & it came from a local violin/bass shop. It was a trade in. What can anyone tell me about these strings?
