Wim,

Is this a Samick?? If so, check the underlever pinning.

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?
