Guitar Maintenance & Repair

Guitar maintenance and repair guides from Sandy Music Lab show how to set up, clean, store and fix acoustic and electric guitars, from adjusting action, intonation and truss rods to repairing loose jacks and dead pickups.
Start with how to clean and maintain a guitar, the routine that prevents most problems. Then use the troubleshooting guides when something goes wrong: buzzing strings, action that is too high, a guitar that keeps going sharp, a loose input jack and noisy pickups.
Protect your guitar between sessions with how to store a guitar, how to keep it from cracking and how to prevent a warped neck. Each guide lists the tools and steps, and tells you when a job is better left to a tech.
