Paul, Jean-Luc, etc. This winter the dealer that I work with has had several cases of bobbing hammers, but mostly in the cheaper studio pianos. I have found myself adjusting the let off button on many of these instruments, and varying from 5-6 keys to an entire section. This seems to do the trick in the store, but it may prove interesting when these instruments have been in someone¹s home for a season or two. Would addressing the issue by raising the keys be a better solution? Or might that lead to leveling issues in a year or so?
