Yea mine is fixed, for me it was the module itself. It needs to be ever so slightly wider so that the groove aligns perfectly with the string when it rolls over. I thought about getting another module but feared it may be the same. Shimming it ever so slightly solves the problem so I don't understand why Bear wouldn't address this issue if so many people have it. All they need to do is make sure the modules fit more snug without any gap(again were talking thousandths) and everthing would be great.
