Searched a bit and didn't spot anyone asking this, what all do you use for marking which adapters belong to which pedals? (Or any electronics, really.) I have two 18V negative tip, one 12V positive tip, and even the EHX pedals want 9.6 rather than 9. I figured a wrap of colored electrical tape near the adapter tip and a bit on the back of the pedal would work well enough, but short of getting a fancy isolated supply with a dozen outputs and building an actual board, I'd just want to be extra sure I'm not frying a pedal.
