It is hard deciding which power supply is the best for your pedal board. Whether you are looking for a cheap PSU to power one or more guitar effects or a power bank that powers your whole pedalboard, we can help you decide on the best pedal power supply for your needs.


When you have a pedalboard full of effects, changing batteries regularly can be expensive over time. It might be more cost-effective to invest that money into a power supply that has many benefits over using batteries. Some pedals do not perform at their best if they do not have enough power being supplied. So for that reason, it is highly recommended to use power supplies if you're using multi-fx pedalsdelayreverb pedals or loop pedals. They're known for consuming 9v batteries pretty quickly.

If your battery is starting to get low, your pedal might start to sound a bit dull and could completely ruin your sound! The right power supply will consistently deliver the optimal amount of power, so that you are always sounding as best as possible. Batteries can be unreliable - imagine running out mid-song and having to find your spare. Or even worse - not having a spare!

main benefits of a pedal power supply

In summary, the benefits of a power supply over batteries are:

  • Reliable, consistent power supply
  • Your power supply will never 'run out' of power
  • your pedals will run at full capacity
  • No sag in your sound
  • your board is less likely to die on you mid gig!

Are there any benefits to batteries over power supplies?

Even though in most cases using a power supply does indeed provide an advantage for the guitarist, in some cases a 9v battery will do just fine, for example, when it comes to fuzz or wah pedals, they can actually be better than a power supply!

For instance, wah pedals take batteries rather well - there's no need to plug one to a power supply, as battery can last ages on a wah. It'll also free one output of the power supply, for a pedal that may need it more!

And Fuzz pedals are widely believed to sound better when using batteries rather than power supplies! They actually interact with the battery, which can change the tonal quality of the fuzz. This is especially true of vintage-style fuzz pedals, such as Tone Benders or Fuzz Face models.

Most guitarists agree that carbon zync batteries make a fuzz pedal sound better than an alkaline battery, and some guitarists will tell you they can even tell the difference when using different brands of alkaline battery, which can give more, or less, high-end definition. But that's not all: there's tonal differences generated across the life span of a battery, affecting and ever changing the sound of your fuzz pedal.

Some guitarists actually prefer the tone of a fuzz pedal with a nearly flat battery, such as Duane Allman, who was said to use a nearly-dead battery on his Fuzz Face, for a "voltage sag" tone, providing a lighter, "creamier" fuzz. Some pedal power supplies actually have the option to recreate this 'sag'. The Voodo Labs pedal power 2+ for example has a connection with the option to drop the power from 9V to 6V, which recreates that sag for fuzz pedals. 

However, if you're a gigging musician, the best way to ensure you can rely on your pedals is to use a power supply!

Benefits of batteries over a pedal power supply

In summary the main benefits of a battery over a pedal power supply would be:

  1. Less cost up front (but is it really worth the risk?)
  2. Sag tone can be achieved with a dying battery
  3. Great option for small pedal boards where you don't have room for a pedal power supply

HOW DOES A DAISY CHAIN WORK? Should I use a daisy Chain for Pedals?

A daisy chain is a great way to power multiple pedals on a smaller board, if you don't have room for a pedal power supply. Daisy chains are often used on beginner pedal boards and are ideal for those just starting out. 

However, we would not recommend them for a full touring pedalboard as they do not supply isolated power. This means that you may get some sound interference or 'buzz' when you're playing on stage. 

They are great for beginner pedalboards and when you're just finding your feet with pedals though. 

So how does a daisy chain work? 

A daisy chain takes pedal power leads and chains them together (usually 5) and powers all your pedals from one power source i.e. a 9V plug. 

You need the following to daisy chain your board:

You need a 9V DC Power Supply

TOURTECH 9V DC Power Supply, Universal 1000mA
TOURTECH 9V DC Power Supply, Universal 1000mA

plus a 5-Way Daisy Chain Pedal Power Cable

TOURTECH 5-Way Daisy Chain Pedal Power Cable
TOURTECH 5-Way Daisy Chain Pedal Power Cable

If you are using a few standard 9v guitar pedals such as BossIbanezEHX or MXR then the daisy chain method will safely power your pedals without breaking the bank. The cheapest way to power your pedals would be to:

  • Find a cheap 9v guitar pedal power supply such as the TOURTECH 9V DC Power Supply.
  • Connect a Daisy Chain cable to your PSU - you will now end up with enough plugs to power 5 guitar effects.
  • Double check the back of your pedal and make sure it is compatible with the power supply. If so, plug and play!

Pros and cons: If you daisy chain too many pedals from one power supply then it might not power some pedals correctly. Ensure that your power supply has enough mA (milliamps) to exceed the total mA of all your pedals added together.

If you are unsure, feel free to drop us a question at the bottom of the page.

Pros: Cheap, compact, easy to setup. 

Cons: Can't use non-standard pedals, power drain throughout the chain, so you're pedals might not sound amazing. 

WARNING: you can easily find multi-voltage power supplies on the high-street, but you must avoid those - they were not made for fx pedals and can often cause unwanted hum or potentially damage your pedal.


In case you gaven't noticed, the benefits of a pedal power supply outweigh any cost. We also thoroughly recomemnd them. 

If you want to power more than 5 pedals or use pedals that demand special requirements, then a power bank is the best way to go. Pretty much 9 out of 10 (if not 10 out of 10!!!) professional artists can be seen using power banks on their pedalboards. This is because they're extremely reliable and supply your pedals with the right amount of power so they sound how they should do!

Most pedal banks have at least 5, and often more than that, of outputs to power different pedals. Usually, the outputs are for fx pedals that require 9v (the standard, as featured on Boss pedals). However, as pedals that require different voltages become more popular (usually by "boutique" brands) some power banks now feature extra voltage outputs. For example, the Voodoo Lab Pedal Power 2 Plus FX Power Supply offers different popular milliamp combinations with 9v, 12.3v, 14.5v, 12v and adjustable 4v-9v . Perfect for powering demanding effects such as some Strymon, Eventide, Line 6 and TC Electronic pedals.

The MXR DC Brick is always a very popular and reliable choice for many guitarists. All of the outputs are isolated, meaning any unwanted noise creating by chaining different effects together is removed completely. If you want the best performance out of your pedals with no extra noises, a multiple output power supply is definitely the way to go. They can be quite bulky, but many pedal boards such as Pedaltrain have brackets to fit them underneath your pedalboard, completely out of sight. 

Pros: Isolated Outputs, Versatile, Best Performance, Reliable. 

Cons: Expensive, Large.


After a quick look at the three different methods, it all comes down to your own needs.

Battery: If you're only powering 1 or two pedals then this might be a good option for you. Or if you want to risk your power dying - go for it! 

Daisy Chain: If you are powering 5 or less than 5 pedals and want to save money, go for a daisy chain. However, we wouldn't recommend this for professionals as the power to each pedal won't be isolated and could result in a slight hum.

Power Bank: If you have any non-standard pedals, use more than 5 or want optimal performance out of your pedals then an all-in-one power supply is the best. There is no doubt that they are superior compared to daisy chaining your pedals, and are essential for professionals.


In this list, we'll round up 8 of what we think are the best pedal power supply options that are reliable, provide the level of clean power you need and are great for professional set ups. 

In summary we think the best pedal power supply options are:

  • Voodoo Lab Pedal Power 2 Plus FX Power Supply
  • MXR M239 ISO Brick Mini Power Supply
  • Strymon Ojai Power Supply
  • MXR M238 ISO Brick Power Supply
  • Voodoo Lab VL-PPMEX Pedal Power Mondo
  • Strymon Zuma Power Supply
  • Voodoo Lab Pedal Power X4 Power Supply
  • Truetone 1 Spot Pro CS6 Power Supply


The Voodoo Lab Pedal Power 2 Plus FX Power Supply is an industry standard pedal power supply, used by everyone from Arctic Monkeys to Queens of the Stone Age. You need to be able to rely on your pedals at all times and the pedal power 2 plus is one of the most most reliable power banks ever. With 8 outlets, you'll have more than enough space to power your board.

The cool thing about this pedal power supply is that you can not only power 9v pedals (most pedals are 9v powered) you can even power 12v, 12.3v and 14.5v pedals and even combine two 12v outlets to supply power to any 24v pedals you may have - ideal for those with vintage Electro Harmonix deluxe memory man delay pedals. You can also change the amount of power running to two of the outlets from 4v to 9v - perfect if you have a fuzz pedal and want to enjoy that power sag sound.

If you're looking for a reliable power supply to power your pedals - this is a great starting (and ending) point.

2. MXR M239 ISO Brick Mini Power Supply

Another extremely reliable pedal power supply comes in the form of the MXR M239 ISO Brick Mini Power Supply. Another great pedal power supply that not only allows you to enjoy hum free power, but is set up to provide four outputs of 9v of power at 300mA and a fifth output which is switchable between 9v and 18v for up to 800mA. 

The bright LED's also let you know that each pedal is recieving power correctly. You also get a cable to provide power from 2 outputs to one pedal - ideal for those who run an 18V pedal. 

There are enough outputs so you can power a variety of different pedals safely and the fact each output can handle both negative and positive grounds make sit great for vintage pedal owners. Each output is isolated too, so each pedal has the correct amount of power flowing into it ensuring you get the best sound.

Finally, it's also small enough to fit under your pedaltrain boards or sit comfortably on your pedalboard without taking up too much room.

Current (mA) plays an important factor when it comes to setting up your guitar pedals. As a general rule, most pedals such as drive, fuzz and distortion can function correctly with a lower current - somewhere around the 20mA mark.

If you have too much current flowing into your pedal, it won't really make a difference as the pedal will draw what it needs from it, however if you don't have enough mA to power your pedal, the pedal will either sound weak or may not turn on at all. 

Strymon pedals require a higher current (mA) than others to run correctly so rather than making people carry around separate mains operated plugs the team at Strymon put together this little wonder.

The Strymon Ojai Power Supply is a high current power supply that provides your pedals with more than enough current to operate correctly. Each pedal gets 9v and 500mA of juice flowing into it ensuring your pedals sound exactly how they should do.

You can power up to 5 pedals at a time, including the likes of the Strymon TimelineBig Sky reverb or any other 9 volt powered pedal in full confidence it'll sound how it's supposed to. Touring musicians will appreciate this power supply too as it's got an automatic international power compatibility built-in.

This means you can enjoy perfect sounding pedals anywhere in the world. In addition, if you have a small selection of Strymon pedals, this is the best power supply for you.

We love the MXR M238 ISO Brick Power Supply as it provides 10 outputs with varying current and draw capabilities so you can power a variety of different pedals including 6, 15, and 18-volt pedals – best of all you can adjust the outputs to suit your needs so you're not limited to these voltage outputs!

For those who like the sound of a “sag” fuzz, you’ll love the ability to emulate voltage “sag,” as the 6 Volt setting gives you a drained battery effect. There’s also a range of your regular 9V power outlets too, so you’re covered for regular 9V pedals! If you’re on a limited budget and have a selection of different styles of guitar pedals this is one of the best power supplies for your pedal board as it’s not only quiet, with noise free operation thanks to the isolated outputs, but it’s also just over £130, so it won’t break the bank.
