Play the note, listen for the annoying sounds, and let the weight of your finger rest on the damper head. If the sound completely dissappears, adding weight to the underlever may work. However, if no change is observed with the added weight of your finger, no amount of lead in the underlever will do you any good. I have found in the past that the damper material may not be cut correctly. The result is that, even if the damper seems to be aligned properly, visually, one of the strings may still sustain. Make sure that the sustaining sounds are coming from all three (or two) strings and not just from one. If it is coming from only one of the strings, there may be irregularities in the damper felt. I once had to 'shave' one side of some trichord material to get the damper to rest evenly on all three strings. Unfortunately, the cosmetic effect of 'shaving' was less than perfect but not completely objectionable. Incidently, the dampers now work very well, although I will likely replace them with better quality material in the future. Laurence Beach Vancouver BC Canada.
