Most etc pedals require 9V one of two people from a battery or exterior power supply. If you have a 12V adapter, you could wonder even if it is you have the right to use the to power your 9V guitar pedals.

You are watching: Can i use a 12v power supply on a 9v

In most cases, friend cannot usage a 12V adapter to strength a 9V etc pedal. Using a 12V adapter top top a pedal designed come only handle 9V can totally destroy it. There space some etc pedals constructed to handle voltages higher than 9V. Those pedals will work-related perfectly fine v a 12V adapter. Inspect the pedal’s manual prior to you shot plugging a 12V adapter into any type of pedal.

Before friend plug any kind of adapter right into a etc pedal, it’s necessary you know the power requirements of the pedal. Voltage is only one component of the snapshot and also if you gain the voltage right, it’s feasible for a strength supply to damage your pedal. Uncover out whatever you would want to know about powering your guitar pedals in this guide.

Running A 12V Adapter ~ above 9V guitar Pedals

Running a etc pedal designed to only manage 9V v a 12V adapter can potentially damage your pedal. If the capacitors inside the pedal aren’t designed to handle 12V and also you plug a 12V adapter in, they’ll burn out.

Some guitar pedals do have actually overvoltage protection, yet that doesn’t median the pedal will certainly work over the preferably voltage. If girlfriend plug a 12V adapter into a pedal with overvoltage protection, your pedal mightsurvive, but the overvoltage defense will probably burn out. It may burn out immediately, or it might take part time before it fails.

Before girlfriend even consider plugging a 12V adapter right into your pedal, discover out for sure whether the pedal is designed come handle much more than 9V. Most pedals aren’t. Review through the pedal’s manual and also if it just says 9V,do not plug a 12V adapter into the pedal.

There space plenty of forum short articles out over there of guitarists speak they plugged a 12V or 18V power supply right into their pedal and while it functioned or a work or two, it eventually shed out. So even if girlfriend plug it in and it functions fine, your pedal may burn out.

Think that voltage together the lot of water you trying to push through a garden hose. If you connect a garden hose to yourhome’s water outlet, the water tap will have the ability to easily manage the press of the water. However imagine connecting a garden hose to a fire hydrant. The lot of push would soon burst the end offof the hose or separation the side. A garden hose (9V pedal) is not designed to manage pressure indigenous a fire hydrant (12V adapter).

It’s the same with voltage and your etc pedals. Make the efforts to affix a 12V or 18V strength supply to a 9V etc pedal is asking for major trouble.

If the pedal is only designed to manage 9V, to buy a 9V power supply(link to Amazon because that a variety of various 9V adapters and devoted power supplies). Lock cheap and also will critical a an extremely long time.

The listed below photo reflects the different types of power provides you can use on guitar pedals:


In this guide, I describe how to decide which type of strength supply might suit her needs. If she trying to usage a 12V adapter since you don’t have actually a 9V adapter, check out through the guide to find out what kind of strength supply you need to get.

Running multiple Pedals native One 9V Adapter

If you currently have a 9V adapter and also buy an additional pedal, the an excellent news is that you don’t should buy one more 9V adapter. It’s feasible to usage the very same adapter to power both pedals.

You can power multiple etc pedals native one adapter utilizing a an approach called Daisy Chaining:


Daisy chaining is as straightforward as purchase a connector command that enables you to plug multiple etc pedals right into your 9V strength supply.

To learn exactly how to correctly daisy chain your pedals, read through this an extensive guide.

Guitar Pedals That have the right to Accept more than 9V

While many guitar pedals only run on 9V, some pedals are designed come accept greater voltages. The pedal will either label what voltage selection it can handle top top the pedal, or you could need to examine out the manual.

The listed below photo mirrors what to look for on your pedal prior to you plug a 12V or 18V strength supply into your pedal:


When a pedal claims “9 – 18V”, it way it can accept voltages all over within the range. That method you have the right to use a 9V strength supply, a 12V supply, or an 18V it is provided without any type of problems.

A usual example that a guitar pedal that accepts 9 – 18V is the Fulltone OCD.


Overdrive pedals choose the OCD often allow greater voltages because a greater voltage can increase headroom. This way you’re able to get greater volumes out of a pedal before it beginning to break up.

Higher headroom is good for guitarists that like very transparent overdrive pedals. A higher voltage (if your pedal is draft to manage it) can provide you much more room to boost your signal there is no breaking the tone up.

The Fulltone OCD is famous partly because it walk sound a lot far better at greater voltages. Countless guitarists operation their OCDs at 18V to provide it the highest headroom possible.

Another common type of pedal that may advantage from greater voltages is fuzz pedals. Many fuzz pedals will certainly sound various when you operation a greater voltage with them.

On the front of the Wampler Fuzztration (find out an ext about the Fuzztration and other fuzz pedals here), you deserve to see it accepts anything indigenous 9V come 18V:


Some guitarists like the sound that a fuzz pedal v a higher voltage, when others favor to stick to 9V. If her fuzz pedal is recognized to handle higher voltages and also you have a 12V adapter, you have the right to plug that in and get an idea even if it is you favor the sound or not.

Try to switch in between a 9V strength supply and a 12V adapter and also listen for any differences in tone and headroom. Greater voltage doesn’t always mean better tone, so run a check to uncover out what friend prefer prior to you decide on a voltage for her pedal.

Here space some instances of guitar pedals recognized to handle greater voltages:

Fulltone OCD (9 – 18V)Wampler Fuzztration(9 – 18V)Most MI Audio Pedals (9 – 24V)MXR Flanger (18V)MXR stereo Chorus (18V)Pigtronix Envelope Phaser (18V)EarthQuakerDevices The depths (9-18V)

There room far more guitar pedals than what I’ve listed above, so prior to you shot plugging a 12V or 18V adapter right into your pedal, check the pedal’s website and also read the manual. Don’t destroy your pedal by overpowering it with voltage it wasn’t designed to handle.

As you deserve to see indigenous the over list, some pedals enable you to attach differentvoltages come the pedal (eg: Fulltone OCD), while others call for a specific voltage (eg: MXR Flanger needs 18V only).

The main allude to remember right here is to just plug a 12V or 18V adapter right into your pedal if you 100% certain it is designed to handle it. Electrical power is not something come play about with. Execute research on her pedal or buy a 9V adapter to play that safe.
