Piano bad regulation

Bad regulated piano action is just like wearing a pair of uncomfortable shoes or driving a
poor aligned car.

Here are some pictures showing you some of the culprits.


Hammer heads are not aligned

Hammer blow distance too far

Improper key dip

Uneven hey height


Improper felts and clothes

Rocking keys without bushing felt support

Bad measurements of back check (too far)


And so on... A time consuming task to get  it done properly

    1. hi it depends on minor or heavy regulation
      have to see on the spot what happen
      it will cost much higher if felts and
      clothes need to be changed due to wear and tear
