Properly power your 18-volt pedals with an adapter you can count on.
The Dunlop ECB004 18-volt DC Adapter is a quiet, well-regulated power supply that powers most effects pedals that run on 18 volts. With 1000mA of current, the ECB004 can even run power supplies such as the DC Brick. 2.1mm by 5.5mm positive barrel with negative center.
Note: Be sure to check the label on the power supply to ensure compatibility with your effects pedal. ECB004 adapters manufactured before summer 2011 had a current rating of 150mA and are NOT compatible with the DC Brick. Newer ECB004 manufactured summer 2011 or later, which are marked with a current rating of 1A (1000mA), can safely be used with the DC Brick.
