Several things can be slightly adjusted to get there, compromising along the way. I almost ignore specs, just consider them part of the equation. Checking closer, increase dip a bit by gang raising balance rail, you could decrease blow if you wanted giving you a better butt angle for escapement (but that's not quick), set let-off little further, make sure minimum lost motion. Yamahas are worse with this in the lower tenor. Many times, weakening the damper springs is the only thing to get it all out (had a few Chinese pianos like that). Fastest, easiest solution is to recommend a tech to her in the area that you don't like and call him "the striking twice specialist".

Hi folks, Tuned a yamaha m-450 (new) a month ago, woman calls back two weeks later and says the piano sounds "twangy". I get there today and she says it's really the way it's playing that is the problem. Says hammers are striking twice, and I ask her to play something for me. She is playing sooo softly she is barely pressing the keys down, while using the sustain pedal as well. I explain what is meant to go on in the action, jack and escapement etc., "well... my old piano never did that". Piano is right on by Yamaha specs, and plays well (when played normally). I set the letoff at about 3-5mm from the strings and it improved the situation. Oh, she also wanted to know why the tenor dampers weren't in a straight line like all the others.(I wanted to scream). What would you guys do besides what I did to correct the problem? Rick Ucci/Ucci Piano -------------- next part -------------- An HTML attachment was scrubbed...
