Powering 5 high-current draw effects pedals?



Asked by: Lena Keenan

How much mA does a pedal need?





Modern digital pedals – like Strymon- or Source Audio-effects – generally need between 200 and 300 mA. Eventide-effects tend to be quite power-hungry, needing currents between 400 and 500 mA. More than 500 mA are usually only required by pro-grade multi-effects or some pedal-sized preamps.

How many milliamps do pedals use?

Current is typically notated in milliamps (mA), and most standard pedals require less than 100 mA. Digital pedals often require a much higher current to operate correctly, generally 200 mA to 1000 mA.

How do you power up multiple guitar pedals?

If you already have a power supply unit that has a high enough current rating to power all of your pedals, it is very cheap to buy a daisy chain cable to connect to your existing unit. You simply plug the connector from your power supply to the daisy chain and you’re good to go.

Is 100mA enough for guitar pedals?

Remember that the power supply you use should provide at least the same amount of current as the pedal draws. So if your pedal has 100mA as the current draw, your power supply must provide at least 100mA. It’s perfectly fine if your power supply has a higher current written on it.

Do milliamps matter on pedals?





The milliamp rating of a power supply is a measure of how much it can supply. The milliamp rating of a pedal is how much it uses. All that matters is supply exceeds demand. The 230 vs 220V rating probably means nothing.

Can I use 500mA instead of 100mA?

For example, putting a 500mA pedal on a 100mA power tap would cause it to act erratically and probably shut down — it might even damage the pedal. Conversely, sending more milliamps than needed to a pedal is fine.

How much current does a guitar pedal need?

Most pedals require 9v DC power and have a very low current requirement but pedals to watch out for include powerful digital pedals like the Strymon or Eventide pedals.

Can I use a power supply with higher milliamps?

Yes, sure. If the connector is the same and the voltage is 12V. The ampere value of the new power adapter should be 2A or greater.



Does amperage matter with guitar pedals?

Your power supply must meet or exceed the pedal’s amperage requirement, usually measured in milliamps (mA). Not doing so could cause irregular performance or even damage! A milliamp meter is useful to view the exact amperage draw of a pedal. This can prove important when configuring and assembling your pedalboard.

What power supply do Boss pedals use?

BOSS PSA-120S Power Supply

BOSS PSA-120S Power Supply



The PSA series is the recommended power supply for products including all new BOSS compact and Twin pedals, multi-effects and more.



How much power does the HX stomp need?

The HX Stomp has a power draw of about 800-900 mA, most power supplies will have 9v 500 mA or higher, these are the outputs you are looking for on a power supply. Power Supplies like the Cioks dc7 will have 9v 660 mA, this will not hurt the stomp.

Do milliamps have to match?

No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.

Can I use a 12V power supply on a 9V guitar pedal?

If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.

What pedals can run at 12V?

Most analog pedals can run on 12V with zero problems.



What pedals can share power?

So it's like it goes into one tap. On the power supply. And then it spreads out to two different connectors on the end. And what I'll do is I'll you know plug in the pedals.

Can a 9V power a 12V?

It depends on whether your power supply is regulated. If you need regulated (stable) 12V, and the 9V supply is unregulated, it could give you up to 14V or slightly higher when not loaded. Chances are it will work, but we don’t know for sure.

How many pedals can you daisy chain?

You can run up to 15 pedals on one power supply. Snark makes some great products. I run 6 pedals right now, I will run more later on. I have had ZERO problems with this daisy chain set up or the power supply.

Can daisy chain damage pedals?

Daisy chains will not harm your pedals. General electrical issues can crop up, particularly if you use the wrong kind of voltage of milliamp load, but that’s going to depend on which pedals you have and how they’re connected to the daisy chain.
