I have recently started to use gut for the mains, I have a klippermate and it leaves a haze where the the pully grabs it. It also has the same problem where I clamp it. My question is does this shorten the life of the string and does the better stringing machines have the same problem? I also broke a knot tying the the last main. I scabbed a short piece and was able to tie off with only a small knot outside of the last main. This should not be a problem since I own It. Does this happen with gut alot?
