Use your wire bending pliers and put a little more kink in both bends, see what happens. I think it's better to find out if that is the problem before making any bends. Here's a quick diagnostic: With one finger under the underlever, push the damper up. You can feel friction either on the way up, or by the way it follows your finger back down (or doesn't). Hold the damper a small amount off the strings with one finger under the underlever. With one finger of the other hand, reach up right under the guide rail and push the wire gently to the right and to the left. If it doesn't move one way or the other, or if the head moves opposite from the way you push the wire, the bushing might be tight. If it does move and there is side pressure against the bushing, you can feel it. If there is too much (you develop a feel for how much is too much), bend the lower bend away from the side which has too much pressure (there should be a tiny bit, however). Step on the pedal. If the damper now travels towards one of its neighbors, correct it at the top bend. Check the pressure again to see if it needs refining. If all this doesn't turn up a problem, NOW is the time to pop out the damper and wiggle the top flange and underlever in turn to see if either is tight. Your fingers are amazingly sensitive in this regard, especially in a go/no-go sort of way. Bob Davis -------------- next part -------------- An HTML attachment was scrubbed...
