The RL15+ is an evolution of the RL15 model.  It is characterized by the same shape and contours, with a slightly wider lower bout and longer body.  With the increase in the volume of the soundbox, comes a slightly lower fundamental tone, and more volume.  The basic construction, layout, bracing, etc, is otherwise identical to the RL15.
