The hammer butt spring I think is stronger than normal to better simlulate gravitational forces that are lost due to the hammer being more vertical than horizontal. The other spring acts kind of like a repetition lever, holding the hammer up while pushing the jack back under. I don't think there are regulating screws - not sure. Notice also that the hammer is regulated to be off the rest rail, as in a grand action. The soft pedal lifts the back of the keys, moving the hammer closer to the strings, while moving the fronts of the keys lower. I have played one of these. It is every bit as good as advertised, which is not something we can often say. -Mark
