The EBS AD9 PRO is a slim-designed power supply that only takes up one outlet spot. It is designed for use with almost every pedal on the market running on 9V DC. The output is short circuit protected and delivers clean and hum-free 9V DC power. Comes with a 2.2 m long flat power cable that is easy to roll up without tangling. North American plug. Works well with all of our products, including Shallow Water (which can be finicky with some switching PSUs).
