Voicing, percussive sound

[florent]

Hi, is it damaging to the pickup if it is so close to the tine that when striking a key hard the sound would be percussive? I guess the tine touches the pickup at that moment, which is weird because it means the distance changed somewhat since when I strike regularly, the sound is clean.

I don't know if it will damage the pickup,but it may nick the magnet or file the very end of the tine,changing the pitch. It sounds like you need to back the pickups off a hair.
