The Stocker is finally here. It won’t change the world but it sure will  make it a better place to play guitar. The Stocker was made to protect  the headstock of your guitar by providing a protective enclosure around  the tuner keys. It installs in fractions of a second and is removed even faster. Made of one piece injected molded plastic, there are no moving  parts or complicated installation procedures. The Stocker was invented  for professional guitar players with busy gig schedules who are looking for simple solutions for protecting their investment and instrument.
