Using the Mike Kerr Jaguar® Bass is easy. Just strap it on, tune the strings using the vintage - style open - back tuning machines, and you're ready to start playing. When playing, you can adjust the pickups to get different tones. The Fender® Custom Humbucking at the bridge gives a more focused and punchy sound, while the Fender® 'Wide Range' Humbucking Bass in the middle offers a warmer and fuller tone. As for maintenance, keep the bass in its deluxe gig bag with tiger embroidery when not in use. Wipe the strings with a clean cloth after each playing session to prevent rust. Check the tuning regularly to ensure accurate pitch. If you notice any loose parts or issues with the frets, it's best to take it to a professional guitar technician for repair. Also, avoid exposing the bass to extreme temperatures and humidity, as this can damage the wood and hardware.
