You've got a great set of guitar pedals neatly aligned on your pedalboard, your instrument cable is plugged in, and you're ready to go.

What do we need? In the words of Tim "The Tool Man" Taylor, we need more power!

Now, you may be thinking, "Huh? I've got a 9v power supply and a multi-plug cable; why would I spend money on an isolated power supply instead of just daisy-chaining my pedals together?" Well, I'm glad you asked.

Sure, daisy chains are convenient and cheap, but they're also unreliable and oftentimes noisy and troublesome.

Since all the power is coming from one source when you daisy-chain, there's no isolation between power receptors, which can lead to unwanted crackles, pops, hissing, and all sorts of undesirable sounds coming from your rig.

Luckily, there are plenty of great isolated pedalboard power supply units available on the market today. Far from being one-size-fits-all, we'll dive into what each unit offers and help you find the right power supply for you.

Kicking off the list is our top pick for the best pedalboard power supply, the Strymon Zuma R-300 5 Outlet Power Supply.

If you're reading this article, there's a good chance you've owned a Truetone 1 Spot before, most likely their classic 9v adapter. Well, consider this a major upgrade.

The Truetone 1 Spot Pro CS12 12-Outlet Guitar Pedal Power Supply Unit provides, as advertised, 12 outlets of quiet, isolated power for your guitar pedals.

Four outputs are switchable between 9-volt and 12-volt operation, and the variable output (4 volts to 9 volts) gives you more tonal control over certain overdrive or fuzz pedals that seem to demand that "dying battery" tone.

The provided mounting brackets work with any Pedaltrain pedal board, and the voltage switching option will let you travel with peace of mind, knowing your sound will be landing wherever you are.

You'll also get all the cables you need to connect your pedals to the 1 Spot Pro CS12: two 26", two 22", four 18", three 12", and one 21" cable. Plus, three adapters for special-needs pedals with reversed polarity and/or different jack types.

Best Pedal Power Supply Buyer's Guide

When you're in the market for a pedalboard power supply, there are some factors to consider to ensure you have a reliable and suitable long-term solution. Here are some things to keep in mind:

Power Output

It's important to check the individual power specifications for each pedal (these are usually indicated in milliamperes or mA) and add them up to find the total power needed.

Make sure the power supply you choose can deliver sufficient power to handle all your pedals.

Voltage Options

Verify the voltage requirements of your pedals. Most pedals operate on 9V DC, but some may require different voltages (e.g., 12V or 18V).

Ensure that the power supply you select offers the required voltages for your pedals.

"Isolaaaaaaaation"

Isolated outputs provide dedicated power to each pedal, reducing noise and interference. This feature is especially important if you have pedals with sensitive electronics or if you want to minimize any potential audio issues.

Look for a power supply with isolated outputs to maintain signal integrity.

Number of Outputs

Consider the number of pedals you plan to power and choose a power supply with sufficient outputs. It's a good idea to account for any future pedal additions so you don't have to upgrade your power supply later.

Physical Size

Ensure that the power supply fits your pedalboard or mounting system. Some power supplies are larger and may not fit in compact pedalboard setups, while others are designed specifically for smaller pedalboards.

You'll want to consider the physical dimensions and layout of your pedalboard before making a decision.

Frequently Asked Questions (FAQs)

What exactly is a pedalboard power supply, and why should I buy one?

A pedalboard power supply provides electrical power to multiple guitar pedals simultaneously. It eliminates the need for individual batteries or multiple wall adapters, streamlining the power distribution on a pedalboard.

Okay, I get it, but why can't I just daisy-chain these pedals together?

Dr. Ian Malcom once said, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." The context, of course, was cloning dinosaurs or whatever, but the same can be said for power supplies.

No, seriously. Daisy-chaining should be used sparingly and primarily for low-current pedals. It is generally recommended to use isolated outputs whenever possible to prevent noise and interference.

Regulated power supplies maintain a constant voltage output, even when the input voltage fluctuates. This stability helps prevent any potential damage to your pedals and ensures consistent performance.

While not absolutely necessary, a regulated power supply is generally preferred for reliability and pedal longevity.

Can I power different voltage pedals with one power supply?

Yep, as long as the power supply offers multiple voltage options. Many power supplies have outputs with switchable voltage settings, allowing you to power pedals that require different voltages.

Make sure the power supply you choose has the necessary voltage options for your pedals.

Are there any safety considerations when choosing a power supply?

Whenever you're dealing with electricity, it's important to follow the manufacturer's instructions and safety guidelines. Be sure to avoid overloading the power supply by exceeding its maximum current output.

Additionally, ensure that the power supply and its cables are in good condition and free from any damage or exposed wiring to prevent electrical hazards. And if your unit is in need of repair, please leave it to the professionals.

Conclusion

When choosing a power supply for your pedalboard, you'll want to find one that matches your pedalboard setup and meets your power requirements. Remember to prioritize quality, durability, and reliability when making your final decision.

Our choice for the best power supply is the Strymon Zuma R-300, which will handle all of your power needs for a long time. But for players on a budget, consider something like the MXR ISO Brick or Gator GTR-PWR-5.
