Hi,

on my black JP70 I noticed when I push down the trem bar for a dive bomb, when releasing the bar I hear a 'clack' kind of sound coming from the trem, I think the sound comes from the knife edge on the treble side of the strings. This only happens upon releasing the bar after it's been pushed far down (like on a dive bomb).
To me it seems that the knife edge gets mispositioned when the trem is pushed way down, and when released it 'flips' back into its position causing that sound. But there must be friction when that happens, so I am worried by doing this (did that maybe 15-20 times in total or so) I could have damaged the knife edge, but it must have been damaged already to begin with.

I guess it's either the trem post/bolt or the knife on the trem base plate that is not ok and my need to be replaced. I don't even know if this part would be available separately.

Has anybody else noticed something like this on their JP70?

UPDATE:

I think I fixed the problem, I oriented the trem springs differently (see attached pic) and now the noise upon a dive bomb and release is gone.
I had never though the trem springs could/should be oriented this way...it's kinda odd, but it solved the problem....
