How To Tighten Loose Guitar Knobs and Controls

In this episode of “Gibson’s Guide to Guitar Setup and Maintenance,” Gibson Master Luthier Jim DeCola demonstrates the proper way to tighten loose controls. This common issue can be simple to repair with Jim’s tips and step-by-step instructions.
Making sure your controls are tightened correctly can reduce the need for future repairs. Most electronic failures are actually mechanical failures. If the controls rotate too much, they can damage or strain the wires. Controls can work loose from frequent use and from expansion and contraction of the wood caused by fluctuations in temperature and humidity. These repairs can be quickly and easily addressed with a few basic tools and Jim’s instructions.
