I recently tuned a Shimmel 5' 8" grand for a new customer. I encountered a "new to me" challenge. The strings angle downward steeply as they leave the tuning pins. The are then redirected sharpely horizontally as they pass through the agraffes. As I begin to tighten a string I would frequently hear a pin sound. It is similar to the sound heard when breaking a rusty bass string loose. The challenge for me is that I would have to pull the tuning hammer quite a bit before anything changed. All of a sudden I would hear this ping sound and the string would suddenly go sharp. Gently loosening the pin "a micro smidge" and it would go flat. It seems to me that the string is almost "sticking" to the agraffe and then breaking free. This situation is making tuning stability difficult. Once I settle the pin with test blows all is fine until the owner plays the piano (mostly classical music) and then I am getting string movement on some notes. This is probably a very simple issue but I am at a total loss. Any suggestions will be appreciated. Terry Jack Eugene OR chapt
