    I have a laserfibre ms200tt. I usually have the clamps pretty tight, because I'm paranoid of clamp slippage, it has no effect on my duraflex. But today I was using tecnifibre e matrix 16, and the string started flattening in the clamps, so I loosened them up...but how loose is too loose? I have trouble telling if there is clamp slippage, but I don't wanna damage my strings...

    If anyone has any tips for me, please tell me. Thanks, moos.

    LF clamps do not need to be so tight that they flatten the string. They do, however, need to be adjusted frequently to accomodate different string gauges and types. Strings with a heavy and slippery PU coating sometimes require a minute or two of extra care. Take a small scrap piece and place it in your clamps. Close the clamp. If it closed easily with no "snap" feeling, it could be too loose. If you close it with a snap feeling and the string comes out flat, it is too tight. You are obviously seeking a happy medium. They do not need to be overly tight, but they do need to be kept clean! Several strings, especially those with PU, leave residue. If you are meticulous with keeping the residue off, you will be fine. I find a non-acetone nail polish remover works best for keeping the clamps clean.

    To check for slippage, pull tension. Fasten clamp. Attach a piece of a Post -It to the string that is clamped on the side opposite the tensioner. Release tension. Watch for movement of post-it. Markers work too if you don't mind a couple marks on the strings.

    Alcohol is your friend, generally. However, if you string a lot of polyurethane-coated strings, acetone will help clean the clamps and other gripping surfaces. No need for sandpaper. Having said that, I would take a crushed string over a slipping string any day. Don't worry about the whitening of strings like EMatrix when clamped. You can probably feel when you are applying to much clamp pressure.
