Wipe down the guitar and amplifier with a soft, dry cloth after each use to remove dust and fingerprints. For the guitar body, a slightly damp cloth can be used, followed by a dry one. Avoid harsh chemicals or abrasive cleaners.
4.2 String Care and Replacement
Strings can corrode over time, affecting tone and playability. Replace strings when they appear dull, rusty, or if they break. Use the included spare strings or purchase new ones of the appropriate gauge. Refer to online tutorials or a qualified technician for string replacement if you are unsure.
