I'm looking to identify the current draw of my pedals in order to know what better power supply to get.
If anyone can help,here's the lista of what I've got:

Turbo Rat: 7.8mA
MXR Envelope Filter(classic): 1.3mA
Junbo Tonebender: ??
Tremulus Lunne: 15mA
Rebote Delay: ??
Boss Geb7: 20mA
Nautilus(mutron): ??
Madbeanpedals SDX delay: ??
Wamplerpedals B65: 3mA
Turbo Tuner: 43mA
Zvex Sup Hard On: 2mA

My rebote is about 23ma and i saw a post somewhere that showed a similar value. LED current draw can play a huge part in a pedals needs, so peoples results could vary widely.

I put together a little box with a one ohm resistor between two power jacks, measure the (m)voltage drop across the resistor and it's a direct transfer to mA's.

I'm Ok with approximate values.all my builds use LED's.By the Time I get the parts to build it it will be too late.I just wanted an idea more or less.There's no local shop where I live, and it would take ages.

Simple and brilliant idea (and a good use for a plastic enclosure)

I saw the vídeo, tried to do it but didn't work.instead of an open Jack I used a closed one but unstriped.I used the wires.the pedal turned on, but no reading.Did he use any resistor that I've missed!?
