Why Do You Need the Best Pedalboard Power Supply?

Even if you are reading this guide, you are still clueless about the functions and importance of a power supply for pedalboard. That is completely okay, as I am here to educate people, not discriminate.

Right from the start, having a power supply can certainly make the difference to the overall operation and performance of your effects pedals. Without them, your stompboxes might sound too groggy and annoying. More than that, here are the things that you should convince you to invest in this device.

  • Power supplies can replace batteries - A power supply is an ergonomic alternative to batteries. Batteries can work well with pedals, but replacing them from time to time is quite a nuisance. You don't want to run out of your power in the middle of your gig, right? Therefore, a power supply should be your next priority.
  • Power supplies prevent mess - If there is no power supply, your pedals can become an ugly mess. The cables can tangle insanely like you are some kind of a plastic spaghetti. A power supply can keep the clutter to a minimum. The presence of a power supply eliminates the need for multiple wires.
  • Power supplies remove unwanted noises - As much as possible, we want the signal chain to be clean at all times. But sometimes, there are pedals that are innately noisy. Pedalboard power supplies can muffle these noticeable hums that simply destroys the quality of your rig.
  • Power supplies regulate varying power requirements - As I have said earlier, effects pedals have different power requirements. If you have a single power outlet in your studio, that can become a problem. A power supply will allow you to regulate and switch its outlets so that you can match it to the operational specs of your stompbox.

How to Choose a Pedalboard Power Supply

Not all power supplies are created equal. It is a fact that you should always remember whenever you are looking for any viable options for this item. Some power supplies are not compatible with your setup, while others might be too inadequate or overkill for you. But none of these can determine the quality of a power supply? So what are they? Check out the guide below.

Isolated Power Supply

When choosing a power supply, make sure that you can get the one with isolated outlets or outputs. If the power outlets are not isolated, you will still suffer from this problem: noise. This issue typically happens if you are running different effects pedals at the same time.

There is no word that can describe the importance of isolated power to power supplies. A noisy setup that doesn't have an isolated power supply will never be regulated. The issue of noise tends to spike up as the number of stompboxes that you are using increases. A daisy chain connection cannot help with this problem because its reliability is never on point.

As a matter of fact, I would prefer using a 9-volt battery over daisy chains because batteries are still forms of isolated power. But there is no need to this anymore as power supplies can provide you with this kind of convenience. Each of the outputs has regulators that ensures that each pedal you plug on them can get dedicated power for operation.


I am not really particular when it comes to the price of a power supply. I would immediately get something if it can offer the things that I am looking for. But of course, I am not saying that I am the filthy-rich kind. I still consider the price. However, I tend to supersede this factor once I gauge that the power supply can really do the job.

An expensive power supply can offer better performance and versatility. They can provide more outlets and features than their cheaper counterparts. However, that doesn't mean that entry-level power supplies suck already. If you just want something that can support your daily practice sessions, these affordable options are already a good deal to take.

Number of Outlets

Power supplies vary in outlets or outputs. The higher the number of outlets, the more pedals it can support. For those who are using multiple pedals during their performances, it is necessary that they should get a power supply with multiple outlets. Also, it would be great if the outlets can be switched to different operating power. That feature can improve their versatility in dealing with effects pedals that have different voltage requirement.


Since we are talking about pedalboard power supplies, it is essential that we discuss their size or footprint as well. Even if a particular power supply has all the essential features that you need, if it can fit in your setup, it is pretty useless. Most of the time, compact power supplies are preferred over larger ones by hobbyists.

Cluttered pedalboards have no room for bulky supplies anymore. Space will always become an issue when installing an extra power supply. Therefore, you should be considerate enough to size up any power supply that you are interested in getting.

Final Wrap

The best pedalboard power supply can ensure that all of your stompboxes can work harmoniously. If you want a smooth operation while playing with your favorite pedals, get an ergonomic power supply immediately. They can solve all the mess and noise that disturbs you from rocking all out.

There are different options that you can get from this particular device. However, the four units that I have featured here can provide you with a satisfying construction and performance right from the get-go. You can always take the Voodoo Lab Pedal Power 2 Plus as an example. It can offer multiple isolated outlets without compromising its footprint. It can generate a clean signal for your pedals, regardless of their type and voltage requirement.

Of course, the rest of the pedalboard power supplies that I listed here have impressive qualities, too. I am not telling you that they should be your only choices. But it would be better if they are on the list of your priorities in your shopping list.

In the end, I will just hope that I was able to help you out when it comes to choosing the right power supply for your pedals. It always gratifies me to aid fellow guitar players in their search for the best gears for their rig.
