Wouldn't weights only be treating the symptom> Joe Goss BSMusEd MMusEd RPT imatunr at srvinet.com www.mothergoosetools.com ----- Original Message ----- From: wimblees at aol.com To: ilvey at sbcglobal.net ; caut at ptg.org Sent: Sunday, August 02, 2009 9:38 PM Subject: Re: [CAUT] after ring on bass damper David I thought I could solve the problem that way, too. But on all Samick products, there are already two weights in the levers, and there's no more room to put any more.

I'd check the weight/spring tension on the damper. Is it different than the dampers around it? I have a Sty D that has some damper over-ring, not isolated. I'm thinking the bass dampers don't have enough damper weight/tension...is there measurement for this?
