Using your Charvel MJ Series electric guitar is a breeze. Just plug it into an amplifier, adjust the volume and tone knobs to your liking, and start playing. When it comes to the tremolo bridge, use it gently to avoid string breakage. For the pickups, you can switch between them to get different sounds. As for maintenance, keep your guitar clean by wiping it down with a soft cloth after each use. Check the strings regularly and replace them when they start to sound dull. Store your guitar in the provided hardshell gig bag to protect it from scratches and damage. And make sure to keep the tuning machines in good condition by lubricating them occasionally.
