Hello. I’m new to pedals and just set up a small board, 4 pedals including Oceans 11, plus a looper. I have the O11 plugged into the 500mA slot in my power supply but after a while it pops itself off. Any thoughts on why this happens? I’m wondering about polarity – the specs say it’s center negative like the other pedals but the symbol on the front is a bit confusing and could be read as center positive. Link to pic of board attached. Thank you!
