Using your Charvel Pro - Mod San Dimas Style 1 HH Floyd Rose Electric Guitar is a breeze. First, tune the guitar using the Charvel® - branded die - cast tuning machines. You can start strumming right away to enjoy the great sound from the Seymour Duncan pickups. When you want to add some effects, use the Floyd Rose® double - locking tremolo. Just be careful not to over - adjust it as it might throw the guitar out of tune. For maintenance, wipe the guitar body with a soft, dry cloth after each use to keep the gloss finish looking great. Check the strings regularly, and replace them when they start to sound dull or feel rough. Keep the guitar in a stable environment, away from extreme heat or cold to prevent the wood from warping. And don't forget to clean the fretboard with a proper cleaner to keep it in good condition.
