Using your D'Angelico Premier Gramercy LS guitar is a breeze. First, tune it up using the built - in tuner. If you're playing in a live setting, use the onboard preamp to adjust the sound to your liking. When you're done playing, wipe the strings with a clean cloth to keep them in good condition. Store your guitar in a dry place, away from extreme temperatures and humidity. Don't forget to change the strings regularly, about every few months, depending on how often you play. This will keep the tone bright and clear. And if you're traveling with your guitar, use a good quality case to protect it from bumps and scratches.
