---------------------- multipart/alternative attachment WIlliam I'd be interested to know if the damper tray pivots are in line with the underlever centers. When they are not in line as are most systems there is more physical weight pulling the entire assembly down into the strings. I have always assumed all models Of Yams had the in line arrangement but ...... Check it out Dale Well, Rick, I must say I would be inclined to concur with the pedal being excessively "thumpy." I just serviced a Yamaha C1 today. The thump of the dampers was really quite bothersome. No amount of limiting the damper travel would do anything here. The felts are in quite good condition, but are a bit firmer than I usually see. My gut is that to make the thumping end, you'll need new (different) damper felts. In my case, it is definitely the damper felts creating the noise, but I would check to see what kind of shape the felts in the pedal box are in and how absorbent they are. I often find poor felts in the pedal box can contribute to that thumping noise. Hope you are able to remedy the problem. Regards, William R.
