Point well taken, Ron. And in the case of a fine piano such as a 1900 Steinway, it is possible and (I agree) proper to add the linkage for the middle pedal which I would realistically estimate 1.5 - 3 hrs to install depending on the dance that's needed. However there are 3-pedaled, lesser quality grands that don't have sostenuto function - they have a dummy spring already or a bass sustain, which in my opinion is a less likely candidate for major concern about the middle pedal. After all, one of the main historical reasons that upright pianos have three pedals is because salesman didn't know what to tell customers who inquired about why the piano had only two pedals (they expected three). - Matt Wynne
