Using your Dean St. Augustine acoustic guitar is easy. Just pick it up, hold it in a comfortable position, and start strumming or plucking the strings. If you want to plug it in, connect it to an amplifier using the Fishman Presys preamp. You can adjust the tone and volume on the preamp to get the sound you like. When it comes to maintenance, keep your guitar in a cool and dry place. Wipe the strings down after each use to prevent rust. If you're not going to play it for a long time, loosen the strings a bit to relieve the tension on the neck. And don't forget to change the strings regularly for the best sound. Also, be careful when moving the guitar to avoid any bumps or scratches.
