Problems with the BOSS DD-3 digital delay pedal usually can be traced down to the 9-volt battery installed in its housing unit. Weak batteries are the cause of no sound or inaccurate sound effects. The battery is best used in conjunction with the AC adaptor. If the cord gets accidentally removed from the electrical socket, the battery will be used as a secondary power source and the other way around. Additionally, alkaline batteries will last longest, between 5 to 10 hours. Look closely at the battery quality and how it's used to repair a BOSS DD-3.

Tips and warnings

  • Use designated shielded I/O cables by Roland to help curb incidents of television or radio interference. You can also try turning the BOSS-DD3 to the opposite side, not facing the television or radio if interferrnace does occur.
  • To enhance performance reliability, use the AC adaptor even when the battery is installed.
  • Remove the battery if you plan on not using the device for a while. Otherwise, the battery could leak inside the housing area of the pedal.
