Maintenance

Proper care and maintenance will ensure the longevity of your DigiTech BP80.

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use abrasive cleaners, solvents, or waxes, as these can damage the finish and internal components.

Troubleshooting

If you encounter issues with your BP80, try the following steps before seeking professional service:

• No Sound Output:
  • Check all cable connections (instrument, output to amp, power).
  • Ensure the BP80 is powered on and the display is active.
  • Verify the Master Volume setting is not at zero.
  • Bypass the unit to check if the issue is with the BP80 or other equipment in your signal chain.
• Distorted or Unwanted Sound:
  • Check input levels from your bass to ensure they are not too high, causing clipping.

  • Ensure the expression pedal is assigned to a parameter within the current preset.
  • Check for any physical obstructions preventing full range of motion.
