Hey everyone. I decided to post here, because it's not a repair, but on a neck of one of my builds. I use two way adjustable double rods like this one. When I install them I make sure both anchor blocks an the top and back fit in tight and I also insert some silicone in the slot. Still one neck has quite some rattle to it when I knock along the neck. That happens when the truss rod is loose or adjusted to create a back bow. When I tighten it in the other direction the rattling is gone, but the trussrod will propably never been adjusted that way. May question is: Is there a way to fix this? I have not installed the frets yet. Any help is much appreciated.
