When I shake my 3 pc rod I detect a tick like something is loose. I experienced this before on a rod just before the tip top came unglued.
I have checked all the guides and tip tip, all seem tight. The grip and reel seat seem tight. I assembled all the pieces seperately (tip to mid section and mid section to butt) shook um...nothing. But when the rod is fully assembled there it is.
I don't notice anything when casting the rod but unlined I can feel it.
