Tips

  • Ideally, use lithium grease for the rocker hinge, but WD-40 works fine.
  • Use silicone grease for the rack as it's designed for plastic parts and won't damage them.
  • Clean your pedal periodically to prevent future squeaking. Store it in a case to keep dust out.

Common Mistakes to Avoid

1. Over-tightening screws

Reason: Excessive tightening can strip the screws or damage the internal components of the wah pedal, leading to further squeaking or even malfunction.
Solution: Tighten screws only until they are snug; avoid over-tightening.

2. Using the wrong type of lubricant

Reason: Using a lubricant that is too thick or thin, or one that is not designed for metal-on-metal contact, can attract dust and grit, exacerbating the squeaking or causing other problems.
Solution: Apply a small amount of a high-quality, light lubricant specifically designed for metal-on-metal contact.

FAQs

My wah pedal squeaks only when I use it, not when it's stationary. What's wrong?
This often indicates a problem with the potentiometer's internal components, specifically the wiper contact. It likely needs cleaning with contact cleaner or may require replacement. Check for any visible damage or debris.
I've cleaned everything and lubricated the moving parts, but my wah still squeaks. What else could it be?
The squeak might originate from the pedal's housing. Check for any loose screws or parts rubbing against each other. Tighten any loose screws or add a thin layer of felt or other non-abrasive material to prevent parts from contacting and rubbing. Sometimes the issue lies within the internal mechanism itself requiring a more advanced repair/replacement of components.
