I just bought a boss DD-3 and it seems when I have it the power supply plugged into it, the battery indicator light is always on and doesnt turn off when I press down on it to turn it off. When I put a fresh battery in it and didn't use the 9v power source, the indicator light wouldn't turn on. The indicator light only was on when the 9v power source was plugged into it, which goes into one of the 8 outputs on my Furman SPB-8, which powers the rest of my pedals fine. Is it where I am placing the delay? Because I am placing it last in my chain before my amp.
I tried using it between my guitar and amp, so it would be the only pedal being used, and the same problem occurred. Can somebody tell me what's wrong with my DD-3?
