Using your Ernie Ball Music Man John Petrucci JP15 Electric Guitar is a breeze. First, plug it into an amplifier using a standard guitar cable. You can adjust the tone and volume using the controls on the guitar. The 3 - way Toggle pickup selector lets you switch between different pickup combinations for various sounds. The tremolo system allows you to add vibrato effects to your playing. When not in use, always store your guitar in the provided hardshell case to protect it from damage. Keep the guitar away from extreme temperatures and humidity as this can affect the wood and electronics. Regularly clean the strings with a soft cloth to remove dirt and grime. You may also want to have the guitar professionally set up every few months to ensure optimal playability.
