Yes, the various blinding specular highlights kind of ruin an otherwise interesting look at a beautiful guitar. The highly polished finish on the instrument is a real challenge for a "hot" flash burst. I think aiming the flash at a larger surface, like a nearby white wall,or a Foam-Core board, or shooting it through at least a 24x24 inch piece of diffusion material would allow you to control/subdue the reflections on the guitar's smooth,shiny finish.
