Abstract: A guitar support strap attached in swiveling relation about a rotation axis held firmly and in perpendicular relation to the guitar body wall, despite the relative thinness and weak construction material of the wall. In a preferred form, a wood screw threadably engaged to the guitar body wall serves as the rotation axis and is held against movement as might tend to allow the screw to work loose or inadvertently disengage from the wall by a steadying force applied in encircling relation about the wood screw.
