I just came across this YouTube vid the other day. I have not found a better setup system. My trem. was fairly OK prior to trying this. Now it stays in tune perfectly. There appears to be a lot of nay-sayers in the comment section, but I'm here to tell you it has been the perfect solution for keeping a floating Wilky-style trem in tune. Make sure you get the intervals correct per string and it should be perfect for you.
