5. Manteniment

5.1 Neteja

Wipe the guitar body and neck with a soft, dry cloth after each use to remove sweat and fingerprints. For deeper cleaning, use a guitar-specific cleaning solution applied to a cloth, not directly to the instrument.

5.2 Substitució de cordes

Strings should be replaced regularly to maintain optimal tone and playability. The HUSH I uses standard steel guitar strings. Refer to online resources or a qualified technician for detailed string replacement instructions if unfamiliar with the process for headless guitars.

5.3 Substitució de la bateria

Replace the 9V battery when the sound becomes weak or distorted, or if the preamp system fails to power on. Follow the instructions in Section 3.3 for safe battery replacement.

5.4 Neck Curvature Adjustment (Truss Rod)

The guitar's neck curvature can be adjusted using the truss rod to optimize string action and prevent buzzing. This adjustment should be performed by an experienced individual or a qualified guitar technician.

• Checking Curvature: Hold the guitar in playing position. Press the first string at the first fret and also at the last fret. Measure the gap between the string and the 8th fret. The ideal gap is typically 0.1-0.2mm.
• Ajust: Use the hidden tuning key to turn the truss rod. Clockwise rotation can correct a concave neck (string too high). Counter-clockwise rotation can correct a convex neck (buzzing due to excessive neck protrusion).
