I'm sure I can't be the only one here, but my pedal collection has far outgrown my pedalboard. And that means that I'm frequently rotating things in and out of the board for different flavors. When they go on the board, they get external power. When they come off, they get a battery so I can still use them. Question is: can I just leave the battery in when I install the pedal on the board? It's a pain to remove. In other words, how many pedals disconnect the battery from the circuit when the external power jack is being used?
