Maintenance Checklists

Possible Causes:

• Low action height
• Worn or uneven frets
• Loose hardware (bridge pins, tailpiece)
• String height at nut too low

Solutions: Check action height first. If action is too low, the instrument may need a setup adjustment. Inspect frets for wear. Ensure all hardware is properly seated. If problems persist, consult a professional luthier.

Possible Causes:

• New strings not properly stretched
• Faulty tuning pegs
• Temperature or humidity changes
• Improper string winding

Solutions: New strings require stretching—tune up repeatedly until stable. Check tuning peg operation and lubricate if sticky. Ensure strings are properly wound around pegs. Monitor environmental conditions.

Possible Causes:

• Accumulated oils and dirt
• Humidity causing finish to soften
• Incompatible cleaning products

Solutions: Clean with appropriate instrument polish and microfiber cloth. Avoid household cleaners. If humidity is high, use dehumidification. For persistent stickiness, consult a professional about finish restoration.

Possible Causes:

• High humidity causing wood expansion
• Neck relief requiring adjustment
• Saddle height too high

Solutions: Check humidity levels first—high humidity often raises action. If humidity is normal, action may need adjustment via truss rod (if applicable) or saddle modification. These adjustments should be done by a professional.

Possible Causes:

• High humidity causing glue failure
• Age-related glue deterioration
• Excessive string tension

Solutions: This requires immediate professional attention. Loosen strings to reduce tension. Do not attempt to reglue yourself—improper gluing can cause permanent damage. A luthier will properly clean and reglue the bridge.
