If the problem is with the higher partials ringing through in the bass section, added mass will probably help. The springs need to be strong enough to firmly seat the damper heads against the strings. There needs to be some (not a huge amount, but some) follow-through when you press against the strings. The damper wedges need to be reasonably well spaced and matched to the strings.

Mass helps the bass strings better; springs help the treble better (if I remember right). --Cy-- ----- Original Message ----- From: vince <mailto:madvinmryk at yahoo.com> mrykalo To: pianotech at ptg.org Sent: Saturday, June 30, 2007 11:49 PM Subject: RE: Damper felt replacement Let's see, the spring action dampens the fundamental more, and mass affects the dampening of the partials...or is it the other way around...no, i think i was right the first time.
