I have owned a 1960 Junior for many years. It has a great neck shape and sounds very good indeed but I find that it's head-heavy on the strap. It has Schaller tuners that were fitted before I acquired it. Could this be the cause of the problem or are Juniors noted for poor balance on the strap? I have always suspected it has something to do with the location of the strap button just below the heel. Any thoughts or possible solutions?
