I have noticed for many years that many yamaha verticals, even brand new 
ones, have bobbling hammers, around the bass break, both sides of it, when played 
softly. Yamahas are certainly great pianos in all other respects, but for some 
reason this is a pervasive problem. It is quite consistent, and not a 
consistent issue on any other brand that I have come across in 20 years of servicing 
pianos. 

I am curious if anyone else has noticed this?

Yamaha tech people told me, a long time ago, to weaken the damper springs. 
That's alot of dampers to weaken! I wonder if there other reasons for this on 
specifically new yamahas? (could be lots of reasons on older pianos)
