Please explain milliamp b.s. for pedals

[romanianreaper]

I have a 1 Spot and has 12 jacks. Ten of them are ones I can use for my current pedals but they range from 100 milliamps up to 500. Most of my pedals recommend under 100 so what should I plug in where? Should I plug the tuner into the highest?

The power supply provides voltage.
The pedals draw current.
Make sure the voltage matches, and the pedal draws less than what the power supply can output.

from how you explained it .... are you worried about sending to much juice to the pedals ?

Yeah, I think that is the main thing. Some of the manuals say 50 milliamps and the jack says 500 milliamps.

Current isn't sent, it's drawn. You can have a 1A source and a pedal will draw the current it needs

You should never exceed the draw limit of the power source. Each line has a limit and the total draw from all lines combined has a limit.

these guys above me basically said what I was going to say ...
when a pedal say " X " milliamps that's the amount of power it will draw from your supplies total output
if your supply says " X " milliamps that's the total amount of power it can provide across the 12 outputs .
so ... if you have 10 pedals that need/draw 50mA each ..... a 500mA supply would suffice .
if you have like a Strymon .... I think those get up over needing 300mA .... anything digital is going to need a lot more juice than a analog pedal

If its the One Spot Pro CS12 then that jack at the opposite end from the two 18v jacks is 9v AC not DC. At least that's how mine is. So there are two 500s, two 250s, and five 100s for nine total 9vdc jacks. I always use the 100mA jacks first if possible so if/when I later add a power hungry pedal the power supply spot is available.

It's been a great power supply.

If it is the CS 12, which it sounds like it is, you can ignore the amperage of the individual outlets as long as you don't exceed the total overall, which is unlikely. Just pay attention to the voltage of the outlets. Too high and it will fry your pedals. Too low and it might not work right. My Boss CE2, despite using a 9 volt battery, won't operate properly unless I use a 12 volt output. Go to 4:40 in this video for further explanation.

Thanks everyone! I watched a video last night and made more sense when I thought about how some of these pedals out there are 500 ma, etc and some outputs are 100 ma.

I ended up plugging my higher ones into the Peterson Tuner, REVV Noise Gate, etc and then my Keeley pedals went into the 100 ma ones.
