Using your Cort G250SE - VVB electric guitar is easy. First, make sure to tune it using the die - cast tuners. You can use the different pickups to get various sounds for different music styles. When you're done playing, unplug the guitar from the amplifier to avoid any electrical issues. For maintenance, keep the guitar in a dry place to prevent the wood from warping. Wipe the strings with a soft cloth after each use to remove sweat and dirt. You can also clean the fretboard occasionally with a suitable fretboard cleaner. Don't forget to check the bridge and tuning machines regularly to ensure they're in good working condition.
