Confused about 9v power supply (?) HELP!

[brucebruce]

If I have a 9v power supply that seems to power my pedals and is 600MA should I be concerned that some all my pedals mention different MAs (some... 200, 100 etc...)? What's the deal?

(i think) as long as the total sum of all your pedals doesn't exceed 600ma you'll be fine

... my main concern is that I'm sending too much power to one pedal and additionally, the guitarist in my band uses BOSS pedals with a BOSS 9v power supply that reads '200MA', yet it powers 5 pedals in a daisy-chain isn't that 5x200MA ? I'm still not sure...

The pedal will only draw what it needs....And if the daisy chain says it's 200ma then it's 200ma total, not adding 200 each time an additional plug is added to the chain.

+1 Even if the total current draw from your pedals exceeds 600mA, your pedals just wont sound right until you get them more power. no damage will be done

So your guitarist has a 200ma power supply for 5 pedals? Thats getting close to, if not, under powering his pedals (Depending on the draw of the pedals).

Basically on the power supply it will display the maximum milliamperes (milliamps) that the supply puts out. On your effects, the sticker (or specs in the manual) will have the maximum that they draw.

For example, if you had a 1000ma power supply and 4 pedals that are 250ma each, then thats the most the adapter could power.

Sometimes you can squeeze more out of the adapter, as your pedals will rarely draw what they display on the sticker. Its a maximum that they will ever draw that is normally displayed.

Its definately better to have more ma than not enough. Speaking from past experience, I was using a power supply that was not rated high enough to supply 1300ma to my Digitech Whammy. I was playing away and all of a sudden the sound crackled out and stopped. When I touched the power supply, it was EXTREMELY over heated. In the long run, that could cause a fire or a breakdown of the adapter. That could lead to a damaged pedal.

Don't be concerned about 'sending to much power to a pedal'. They draw the power, its not forced down their throat. You could happily power a 200ma pedal with a 1300ma power supply. Just make sure you have the voltage right, as in 9V, and get an adapter with a high ma rating so you can daisy chain a few pedals without any worries.

+1 to what Karate Kid says.

Also, pedal only take what they need. So if you have 1000Ma power supply plugged into a a pedal that requires only 50ma, the pedal will not be "overpowered". It will just take what it needs. You still have 950ma worth of gadgets of hook up to your signal chain.
