Roger, Now that is the trick isn't it? When is that moment just before "over voice(d)"? I would have thought that the bright, brassy sound would have a predominance of high partials...What do you mean by a higher ratio of fundamental to higher partials? If I have a Yamaha hammer that is played a lot, where is the compression of the felt happening to cause the bright/brassy sound? Near and around the crown? Does it ever really go down into the lower shoulders? I will be filing a C3's hammers in the next couple of weeks. The filing will even out the tone but it will still be too bright. Where would you suggest I needle? I'm not interested in steaming right now. I would typically be trying to loosen up the upper shoulders...
