Wim, Is this a Samick?? If so, check the underlever pinning. Denis Ikeler -----Original Message----- From: David Ilvedson <ilvey at sbcglobal.net> To: caut at ptg.org Sent: Sun, Aug 2, 2009 12:04 am Subject: Re: [CAUT] after ring on bass damper Wim, If the rings goes away when you add a little pressure to the damper head, you have isolated the problem to that damper. 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?
