Using your Charvel Pro - Mod DK22 SSS 2PT Electric Guitar is a breeze. First, make sure your guitar is properly tuned using the Charvel® - Branded Die - Cast Locking tuning machines. You can adjust the sound by switching between the different Seymour Duncan® pickups. When you're ready to play, strum the Nickel Plated Steel strings gently or aggressively depending on your style. For cleaning, use a soft cloth to wipe the body and fretboard regularly. Avoid exposing the guitar to extreme temperatures or humidity as it can damage the wood and hardware. If you're not using the Gotoh® Custom 510 Tremolo bridge, make sure to keep it in good condition by lubricating it occasionally. Check the strings for wear and tear and replace them when they start to sound dull or lose their elasticity.
