I does depend on the specific pedal, but I would say a good guide is that pedals like
Reverb and Delay tend to be a bit more power hungry given that they are more complex
circuits (a bit of a generalisation) although digital pedals will require more juice.
If it was me and I was limited to 3 outputs I would power the delay and reverb
seperately and then daisy chain the rest. If I had four I'd probably do the noise gate
Not sure if that helps!
