You can also try regulating the lift so that the dampers don't rise or set quite uniformly front to back, i.e. the back lifts first, or the front for that matter (just slightly) so the dampers actually kind of rock down onto the strings rather than fall straight down with the front and back seating at the same time. Changing damper felt may not solve the problem. Also, remember that an insensitive foot can always make a thump and that higher tension in the trap work tends to get the foot to release more rapidly.

I ran across a S&S L (1967) today that had really loud thump when the dampers come back to rest. At one point, I had enough spring tension on that part of the trap work that I could barely press down on the pedal, but the thump was gone!..obviously not the correct fix. I'm thinking that the only fix for this is to change out the damper felt. Are there any other thoughts? I appreciate them. -Phil Bondi(Fl)
