Using your Cort G300 - PRO - MGD Metallic Gold Electric Guitar is a breeze. First, make sure your guitar is properly tuned using the Cort® Staggered Locking Tuners. You can use the 5 - way pickup selector to switch between different tones created by the Seymour Duncan® humbuckers. When you're ready to play, strum or pick the D'Addario® EXL120 strings and enjoy the great sound. For high - position solos, take advantage of the 24 frets. As for maintenance, keep your guitar in a dry and clean place. Wipe the strings after each use to prevent rust. You can also use a soft cloth to clean the body and fretboard. If you need to adjust the action or intonation, it's best to consult a professional guitar technician. And be careful when using the Cort® CFA - III Tremolo bridge to avoid any damage.
