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.
