I have had an Elitist 1965 Casino for 5 yrs. that I bought on Ebay. Cosmetically it is pristine. The set up was fine during that time. However, recently (I live in upstate NY) it developed very slight string buzz on the high E string around the 14th fret. I removed the truss rod cover and found the end piece on the rod is a"bullet" style brass fitting that screws onto the rod end. Is there a special tool for adjusting this rod other than a basic hex wrench?? I just don't comprehend how this rod functions....it seems to me if I want to add relief to the neck I'm just going to undo the brass bullet cap!! Any advisement is welcomed....please excuse the ignorance, all my other guitars are quite simple utilizing an everyday allen wrench....
thanks
