If you’ve ever had a great pedalboard held back by a sketchy power supply, you know how important clean, reliable power really is. Noisy outputs, not enough current for your digital pedals, daisy-chain hum… it all adds up and kills your tone and your patience.
The Voodoo Lab Pedal Power 3 Plus (on Amazon) is designed to solve that problem for good—with enough clean, expandable power to run a serious board now and grow with you later.
If you’re running multiple digital pedals, high-current units, or planning a big board with room to expand, this is very much in your lane.
Overview / First Impressions
The Pedal Power 3 Plus is a high-quality, professional-grade switch-mode power supply from Voodoo Lab. It’s built for modern boards with:
- 10 high-current 9V DC outputs (500 mA each)
- 2 additional configurable outputs
- Expandable power via X-LINK ports (up to 28 pedals total with add-ons)
- Worldwide voltage compatibility (100–240V)
The big takeaway: this isn’t a “barely enough” power brick. It’s designed so you can plug in just about any pedal—especially hungry digital units—without worrying about current limits or noise.
Build Quality & Design
Physically, the Pedal Power 3 Plus feels like a serious piece of gear:
- Aluminum chassis – Solid, rigid, and built to be mounted under a pedalboard. No flimsy plastic.
- Tactile switches – The voltage/current switches feel sturdy and precise, not cheap or wobbly.
- Standard IEC power connector – Uses the same type of cable as most amps and pro audio gear.
That IEC input is a big plus: if the cable gets lost or damaged, you just grab any standard IEC cable and you’re back in business. No hunting for a proprietary adapter.
This is clearly designed to live under a board long-term, survive travel, and just work.
Features & Functions
Here’s what you actually get in terms of power and flexibility.
Isolated Outputs
- 10 x 9V DC outputs
- Each rated at 500 mA
- Fully isolated
500 mA per output is enough to power almost any pedal on the market, including most modern digital units (Strymon, Line 6, etc.), without resorting to hacks or daisy chains.
On top of that, you effectively have:
- 12 isolated outputs total on the main unit
(10 standard + 2 configurable outputs)
Configurable Outputs
There are two additional outputs that can be switched:
- Voltage: 9V or 12V
- Current: 200 mA or 500 mA
These are handy for:
- Pedals that require 12V instead of 9V
- Lower-current analog pedals you don’t want to “waste” a 500 mA output on
- Building a more flexible power layout for mixed analog/digital setups
X-LINK Expansion Ports
This is where the Pedal Power 3 Plus really stands out.
On the side, you’ll find X-LINK expansion ports that allow you to connect Voodoo Lab’s:
- X4 expansion unit
- X8 expansion unit
Using these, you can expand your system to power up to 28 pedals from a single AC mains connection.
In other words:
- Start with the 3 Plus on your board
- Add X4 or X8 units as your board grows
- Still use only one wall plug
If you like big boards—or just like the idea of not having to buy an entirely new power supply when you add pedals—this is a major selling point.
Global Voltage Compatibility
The Pedal Power 3 Plus can accept:
- 100V–240V AC
That means:
- Use it in the US, Europe, Australia, etc.
- All you need is the appropriate IEC cable or plug adapter for the country
No step-up/step-down transformer required. If you travel or tour internationally, this is a big convenience.
Optional Cables & Adapters
Voodoo Lab supports a wide range of power configurations via optional accessories, including:
- Output splitters – Power multiple low-draw pedals from one output (when appropriate)
- Voltage doubler adapters – Combine outputs to get higher voltages (e.g., 24V)
- Current doubler adapters – Combine outputs for more current if needed
- Line 6 HX-specific cables
- Battery snap cables – For pedals that only have battery clips
- Replacement Pedal Power cables of various lengths and plug types
This makes it easy to tailor your power setup to your exact rig without resorting to random third-party cables.
How It Sounds / Use Cases
You don’t “hear” a power supply in the traditional sense—but you absolutely hear it when it’s bad.
Because the Pedal Power 3 Plus is a modern switch-mode supply with isolated outputs and high current capacity, the practical results are:
- Less noise and hum compared to daisy-chained or underpowered supplies
- Stable performance from digital pedals that are picky about current
- No weird behavior when you step on multiple pedals at once
This is especially useful if you:
- Run multiple digital pedals (HX, Strymon, Eventide, etc.)
- Have a large board with many analog and digital units mixed
- Play live and need consistent, quiet operation
- Record and want a clean noise floor
The user who shared this experience runs 12 pedals off the Pedal Power 3 Plus with no issues at all and chose it specifically because previous supplies couldn’t handle the current draw of certain pedals. That’s exactly the kind of real-world scenario this unit is made for.
And if you ever decide to go wild and build a 20+ pedal monster board, you can expand via X4/X8 units instead of replacing your whole power system.
Limitations / Things to Know
A few practical notes to keep in mind:
- You still need to match voltages and polarity.
The supply is flexible, but you’re responsible for making sure each pedal gets the correct voltage and polarity. - High-voltage needs require adapters.
If you have pedals that need 18V or 24V, you’ll likely use voltage doubler adapters or dedicated outputs on expansions. - 28 pedals is the max with expansions.
For 99% of players, that’s more than enough—but it is a practical upper limit of the system.
For most guitarists—even those with fairly serious boards—these aren’t dealbreakers, just normal power-planning considerations.
Final Thoughts
The Voodoo Lab Pedal Power 3 Plus is an excellent choice if you:
- Want clean, reliable, isolated power for a serious pedalboard
- Use high-current digital pedals that overwhelm cheaper supplies
- Plan to expand your board over time and don’t want to buy a new power system every time
- Need worldwide compatibility with standard IEC cabling
It’s not the cheapest option on the market, but it’s built like a professional tool and designed to grow with you. For players who love large boards or just want a power supply they won’t outgrow, it’s a very smart investment.
