Using this Charvel Frank Bello Signature bass is a breeze. First, tune it up using the Charvel® Open - Gear tuning machines. The nickel - plated steel strings in .045 - .105 gauges offer a great feel and tone. When you play, the EMG® pickups will give you that warm, punchy sound. For the neck, if you feel the need to adjust the neck relief, use the heel - mount truss rod adjustment wheel. Just turn it gently until you get the right feel. As for maintenance, keep your bass in a stable environment to prevent the graphite - reinforced neck from being affected by extreme climate changes. Wipe the strings after each use to prevent corrosion. You can also use a soft cloth to clean the body and the chrome hardware to keep it looking shiny. If you're not using it for a long time, store it in a proper guitar case to protect it from dust and potential damage.
