What actually matters when choosing a pedalboard power supply?
Isolated outputs, enough current for your pedals, and reliable build — not how many lights or extra features it has.
Who This Guide Is For
- Guitarists building or cleaning up a pedalboard
- Players dealing with noise or daisy-chain problems
- Anyone trying to understand what a power supply actually needs to do
Who This Is Not For
- Players running only one or two simple pedals
- Anyone looking for the cheapest possible wall-wart solution
Why Power Supplies Matter More Than Most People Think
A noisy or underpowered supply can make a good board sound broken. Daisy-chaining everything from one cheap adapter is the most common source of hum and unwanted noise on small boards.
An isolated supply gives each pedal (or small group) its own clean feed so digital and analog pedals don’t talk to each other through the power line.
What to Look For
- Isolated outputs (not just multiple jacks from one supply)
- Enough milliamps for your highest-current pedals
- Standard 9V center-negative compatibility for most pedals
- Room to expand if you add more pedals later

Best for: Players who want a compact, reliable isolated supply with flexible voltage options
Typical price range: $200–$250. Small footprint and solid reputation for clean power on medium boards.
Check Current Price →Voodoo Lab Pedal Power 2 Plus
Best for: Players who want a proven, widely supported isolated supply for standard boards
Typical price range: $180–$230. Long track record and easy to find cables and accessories for.
Check Current Price →Strymon Ojai
Best for: Smaller boards that still need clean, isolated power without a large supply
Typical price range: $150–$180. Compact and expandable if your board grows later.
Check Current Price →Common Mistakes
- Assuming every multi-output supply is isolated
- Underestimating current draw on digital pedals
- Using the wrong polarity or voltage on a pedal
- Buying the cheapest option and fighting noise later
Frequently Asked Questions
Do I really need isolated outputs?
If you run more than a couple of pedals, or any digital ones, yes. Isolation is the main reason to buy a proper supply.
Can I mix different pedal voltages?
Only if the supply offers switchable or dedicated higher-voltage outputs and you set them correctly.
Is a cheaper non-isolated supply ever fine?
For one or two simple analog pedals, sometimes. Once the board grows, noise usually appears.
Final Thoughts
A good power supply removes a common source of frustration and lets your pedals do their job. Isolated outputs and enough current matter more than brand hype or extra features you won’t use.
Buy once with enough headroom for the board you actually play, and you won’t need to think about power again for a long time.
