I recently tuned a Hamburg L that had a PianoDisc installed. They had replaced the action frame with NY brackets and rails, keeping the wips and shanks. They then added a NY style sostenuto, using, I guess, a NY lyre, and homemade trapwork. It actually worked, but not for the 100 lb. player - you needed to be a gorilla to overcome the bad leverage. Also, the jack tails completely missed the letoff buttons, but it kind of let off anyway. All to have a sostenuto that the PianoDisc couldn't operate, and the owners (not the player) would never use. What a mess. -- Mark Schecter On Dec 28, 2010, at 6:27 AM, John Formsma <formsma at gmail.com> wrote: > > > On Tue, Dec 28, 2010 at 8:00 AM, Ken & Pat Gerler <kenneth.gerler at prodigy.net> wrote: > > > I have also seen grands with a PianoDisc (I believe) system installed and the Sustenuto disconnected because there was no way to modify the trapwork to keep it in operation.
