Hi, Avery, One immediate thought is that the dampers are rising then vibrate side to side causing a mechanical sound. The solution is the bend the wires just above the damper top flange so the wire rides one side of the bushing, or the other, whichever allows the damper to seat properly, without becoming sluggish. Rebushing the guide rail would also be helpful. If the dampers are hard it could be caused by the damper dancing on the string before finally muting. Newton nhunt@rci.rutgers.edu
