Using this Charvel electric guitar is easy. First, make sure it's properly tuned using the Charvel® - branded die - cast locking tuning machines. Plug it into your amplifier and start playing. The EMG® pickups give you a great sound right away. When you're on stage or in a dark environment, use the Luminlay® side dots to find your way on the fingerboard. For the neck relief, if you feel it's too tight or loose, you can use the heel - mount truss rod adjustment wheel to make quick changes. As for maintenance, keep the guitar in a case when not in use to protect it from dust and scratches. Wipe the strings with a clean cloth after each use to prevent rust. Also, check the bridge and other hardware regularly to make sure they're in good condition. If you notice any problems, it's best to take it to a professional guitar technician.
