I got the impression that some people think that I meant the hammer to check high on the back check. That is not da case. I talked about adjusting the height of the back check and checking the distance between the hammer tail and the top of the back check AFTER drop, which then should be 2 mm. In fact the hammer has not checked because we slowly depress the key so that let off and drop take place without the hammer actually bouncing from string into back check. It remains a mystery to me. What also remains a mystery is why a tone improves after installing brand new back checks. We often replace worn back checks completely because it is faster and more economical, instead of replacing the leather. Every time we replace the complete back checks the tone is 'newer'.
