Everytime, I clamp my main strings when stringing they turn a little white where I clamped it. After Stringing, every placed I clamped was whiter. Does that mean I stripped the strings? I have a klippermate. How do I get this fixed? Thanks. PS. I tried to loosen the clamps but it still makes it turn white. Is it the strings? If I loosen it more, Im afraid that The strings will slip out. What do I do?
