Using your Cort Core - PE All Mahogany Acoustic Guitar is a breeze. First, take it out of the deluxe soft - side case gently. Make sure the strings are in tune using the vintage - style open gear tuners with ivoroid knobs. When playing, enjoy the great playability offered by the solid mahogany body and ovangkol fretboard. For a better sound, try different strumming patterns. As for maintenance, keep the guitar in a dry and cool place to prevent the wood from warping. Wipe the strings with a clean cloth after each use to keep them in good condition. Avoid exposing the guitar to extreme temperatures or humidity. If you want to change the strings, use D'Addario® EXP16 Light strings for the best match. Also, check the tuning machines regularly to ensure they work smoothly.
