***? (String manufacturers everywhere)Here's a radical suggestion - Take a piece of 320 or 400 grit sandpaper and wrap it around the string with the grit side against the string. Hold the two ends of the sandpaper between index finger and thumb. Draw the sand paper down the length of the string a few times. See what happens. If it doesn't help you've lost nothing but a few minutes of time, given you were going to replace the string anyway.
