I find that the truss rod on my bass is about as tight as it will go. For fear of breaking it I have stopped tweaking it. I brought this to the attention of the store guys that sold it to me. He said "If it's a problem bring it here." I don't really want to bring it down town so I would like some advice here. I was thinking of completely un-screwing the truss rod and putting a washer over the rod and screwing it back on. I read that the truss rod could compress the wood a little and this would fix it. Am I wrong in my assumption? Help!
