Here's Marshall Lee's Axe Guitar's head stock from Adventure Time! This was made for my nephew who's creating his own axe. This head stock will fit at the top of his guitar neck stock once it's finished. The tuning knobs turn but don't attach to strings as it's just a cosplay piece. Created from Super Sculpy and metal. It's possible to make a real working one so long as you mold the skull around an actual head stock with working tuner knobs. For that you'll need Aves Fixit or Apoxie Sculpt as it's self-hardening and doesn't need to be fired in an oven.
