Unfortunately some of the toughest pedals to bring back to life are digital pedals that no longer power up. This is due to incorrect powering such as too much voltage or the use of a power supply of incorrect polarity. This Boss DD-20 Giga Delay is one such example. There was no power or audio signal but on closer inspection no ICs or voltage regulators were damaged. A replacement of a SMD protection resistor resurrected the pedal with a flurry of flashing lights. This one is a success!
