Using your Charvel Pro - Mod San Dimas Bass PJ IV is a breeze. First, make sure your bass is properly tuned using the Charvel® Open - Gear tuning machines. When you start playing, the DiMarzio pickups will give you a rich and full sound. For different tones, you can experiment with the combination of the Model J™ at the bridge and the Model P® in the middle.
When it comes to maintenance, keep your bass clean. Wipe it down after each use with a soft, dry cloth to remove fingerprints and sweat. Since the body finish is gloss, be careful not to scratch it. Check the strings regularly. If they start to sound dull or feel rough, it's time to replace them with new nickel - plated steel strings of the same gauge (.045 -.100).
Also, store your bass in a proper case when not in use. This will protect it from dust, humidity, and accidental bumps. If you're going to transport it, make sure it's well - secured in the case to avoid any damage.
