Hi,
I've just bought a Caline 5 power distribution pack for a pedal board and I read in the instructions (yes, I hear you, it's not normal to read the instructions first!) there is a potential risk of connecting up pedals with the opposite polarity to the power unit.
I'm still waiting for pedals to be delivered, but is it possible for me to connect up a reversed polarity pedal to the unit without realising it or is the Jack plug different? How would I know?
