I've been trying to figure out what strings I have on my Kay right now, and I have absolutely no idea. The link to the string finder in the stickies didn'g give me anything, and I tried all sorts of combinations. What I've got are strings with yellow silk on both ends, and the ball ends of the E, A, and D strings have a 1cm dark blue, possibly faded black band at the end of the silk farther from the ball. The G is the same, but the band on the yellow silk is is red. They're steel-core strings as far as I know, but the G is the only all steel-wrapped one of the set. The E and A look like they're copper, and the D looks like its both steel and copper twisted together. They're very smooth, and the tension is what I would consider a 'medium-light' but I have no other point of reference, having never played anything but these strings. I know its time to change them because they're completely dead, I just want to know what they are before I take the plunge and slap on a Spirocore Red Mitchell set. Thanks for any help!
