I want to hook up my Boss CS-3 to my power block with my other pedals. I had it hooked up before, but now it doesn't get full voltage to the circuit through the power adapter, but it does get full voltage through the battery side though. I'm not sure how to test the power adapter port on the back of it, but I'm kinda leaning towards that being the problem. Just to be sure it wasn't the cord or the port I tested other pedals in the same spot with the cord and tested other the ports with the Boss Pedal. I'd really like to kill off using batteries, but I would like to leave it stock so I could use a battery from time to time if needed and use the power block almost permanently.
