Q: An allen wrench in a plastic pouch came with my guitar. I’ve looked all over and can’t find any place where an allen wrench this size would fit anything.


A: This allen wrench is use to adjust the neck curve. There are two places where this is done, either inside the body of the guitar toward the guitar neck or at the end of the headstock of the guitar. Moving away from the body after the nut (where the strings get guided off the neck) there usually is a plastic cover that needs to be removed to access the neck adjustment screw.


I recommend that you have a professional guitar technician adjust your guitar neck because it is a very delicate process.
