Truss Rod
A truss rod is a crucial component inside the neck of guitars, banjos, and other stringed instruments. It's like a metal spine that helps keep the instrument's neck straight and allows repair technicians to adjust it when needed. Think of it as a support beam that counteracts the pulling force of the strings, which could otherwise warp or bend the neck over time. Being able to work with truss rods is a fundamental skill for instrument repair technicians, as proper adjustment affects both playability and sound quality.
