Luigi, Because you are dealing with bichords, I would check how centred the damper is. - To check this, observe the damper as it comes back onto the strings, it should look as if the strings are _both_ separating and heading in opposite direction to one another. If it is favoring one side you know that you will need to move the damper head in the direction of the string that is not moving or not moving as much as its partner. - Try the damper guide bushings, if they are worn it's almost impossible to get good clean damping. - Check the straightness of the damper blocks, if they are not lined up nicely it will also cause problems, you may have to pull one off and reglue or glue on another. This is particularly so if you have aligned the damoer head with the string, but the damper felts are crooked, mind you this should show up during regulation with the damper kicking or running to one side. Lots of luck (and skill of course), I just love the feeling of beating recalcitrant dampers!! Mark Bolsius Canberra - Australia ICQ 34689385 ---------- From: "Luigi Lamacchia" <luigi@inmedia.it> Date: Sat, 27 Mar 1999 8:34 AM Holy List, please help me ! I'm running into trouble with the bass dampers of a Bosendorfer 170. As the felt had become noisy, I substituted them all. Everithing was fine but the bass bichords. The decay time is too long. Everything regulated, the damper heads work 90 degrees to the strings, open regularly, etc., but if you play "staccato", the fundamental and the 2° harmonic take too long to decay. I tried many things, i.e. different lenght of the felt, different position, squeezed the felt to make it enter a little more into the bichords, but nothing made it fine. Besides that, my customer says that it's not working as well as before... But before it was too noisy, and it has never had a good damping on the bass, so now I must do something resolutive ! In the LIST we trust... Thank you ! Luigi Lamacchia www.inmedia.it/lamacchia
