A few years ago I went through a similar process of compiling a list of all the pedals I owned.
I didn't measure all of them so some as stated by the MFR and some recorded by me (as noted on the list). However I didn't do a full comparison of "stated" vs "measured" mA.
I haven't updated it in quite a while, and I definitely have acquired more pedals since then. Maybe I'll take the time and do those so I can get them on the list. I only did it so I could keep an eye on total current draw vs what my power supply could handle.
I've been using a 2A supply for a long time and never have come close to that. (even if I turned them all on simultaneously)
My main pedalboard regularly consists of 10-11 pedals.
Which makes me think... have we had a "show us your pedalboard" thread here???
Anyway, here's the list if anyone is interested. (Sorry had to save as .txt to fit file size)
