Using your Charvel Pro Mod San Dimas Style 1 HH Floyd Rose Electric Guitar is a breeze. First, make sure the guitar is properly tuned using the Charvel® - branded die - cast tuning machines. When you're ready to play, you'll notice the speed neck profile makes it easy to move your fingers quickly up and down the fretboard. The heel - mounted spoke wheel allows you to adjust the truss rod easily if you feel the neck needs it. To get different tones, play around with the volume control's push/pull coil split and the No - Load tone control. The Floyd Rose® 1000 series double - locking tremolo bridge system is great for adding effects like dives and harmonics, but be careful not to overdo it as it can affect the tuning. As for maintenance, keep the guitar in a stable environment to prevent the neck from bending or warping. Wipe the body with a soft cloth after each use to keep the gloss polyurethane finish looking good. And don't forget to change the NPS strings regularly, especially if you play often, to maintain the best sound quality.
