Made for a groom from pictures of his real guitar. Made this one just a bit smaller than the original. The tuning keys are thumb screws, Wooden knobs painted with black food color for the volume, etc and the string pegs. The strings are elastic thread. I was able to tighten them after the picture was taken. It is all buttercream icing except the 2 solid pieces (can't remember what they're called) under the strings. They are modeling chocolate painted with gel paste.
