Using your Ernie Ball Music Man JP15 electric guitar is easy. First, make sure it's properly tuned using the Schaller M6 - IND locking tuning machines. Then, plug it into an amplifier. You can use the 3 - way Toggle pickup selector to choose different tones from the DiMarzio Illuminator pickups. The onboard 20db gain boost can add extra power to your sound when needed. When not in use, keep it in the Music Man hardshell case to protect it. For maintenance, wipe the body with a soft, dry cloth regularly to keep the high - gloss polyester finish looking good. Check the strings periodically and replace them when they start to sound dull or lose their tension. Also, make sure the bridge and tremolo are clean and lubricated for smooth operation.
