4. Installation (Setup)
These control knobs are designed for easy installation on potentiometers with a 6.3mm (0.25 inch) diameter shaft. No special tools are typically required for standard push-on installation.
- Verify Shaft Compatibility: Ensure your instrument's potentiometer shafts have a 6.3mm diameter.
- Remove Old Knobs (if applicable): Gently pull existing knobs straight off the potentiometer shafts. Avoid twisting or prying forcefully to prevent damage to the potentiometer.
- Align and Press: Align the new Guyker CKB035 knob with the potentiometer shaft. Apply firm, even pressure to push the knob straight onto the shaft until it is seated securely. Do not force the knob if it feels too tight; verify shaft size.
- Test Functionality: Once installed, rotate the knob to ensure smooth operation and proper control over volume or tone.

5. Operating
Once installed, the Guyker CKB035 control knobs function identically to your instrument's original knobs. Rotate them clockwise or counter-clockwise to adjust the corresponding potentiometer's setting, such as volume, tone, or other effects, depending on your instrument's wiring configuration.
6. Maintenance
To maintain the appearance and functionality of your control knobs:
- Cleaning: Wipe the knobs with a soft, dry cloth to remove dust and fingerprints. For stubborn grime, a slightly damp cloth can be used, followed immediately by a dry cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
- Inspection: Periodically check that the knobs are securely seated on their shafts. If a knob feels loose, gently press it back into place.
- Storage: If removing the knobs for storage or transport, keep them in a protective pouch or container to prevent scratches.
7. Troubleshooting
- Knob is Loose: If the knob feels loose on the shaft, ensure it is fully pushed down. If it continues to be loose, the potentiometer shaft may be undersized or worn, or the knob's internal diameter may be slightly oversized. Consider adding a small piece of tape around the shaft for a tighter fit, or consult a guitar technician.
- Knob Does Not Fit: If the knob cannot be pushed onto the shaft, re-verify the shaft diameter. These knobs are designed for 6.3mm shafts. Forcing the knob can damage both the knob and the potentiometer.
- Difficult Rotation: If the knob is difficult to turn, ensure it is not rubbing against the instrument's body or pickguard. Adjust its position slightly if necessary. If the issue persists, the potentiometer itself may require maintenance or replacement.
