Confirmed it was coming from either the shank or knuckle as the jack pushes through letoff. Switched shanks with a neighbor, to confirm that the sound came from the shank assembly and not the jack/rep assembly or key. With the swapped shank, the sound went away. -Put the original shank back on F1, adjusted the jack proximal and distal...no change -Rep lever height ok -Pinning looks ok. 7 swings on a low bass hammer...a little looser than I'd like, but not terrible -Knuckle still has a good radius. Filed it lightly to see if there was a change, but as I expected, no change Was going to try to repin a bit tighter...but I my pinning tool was in the shop...oops Looked at the shank and hammer glue joint. No obvious issues. Any ideas???
