1. Voodoo Lab Pedal Power 2 Plus – The Industry Standard
Voodoo Lab Pedal Power 2 Plus Isolated Power Supply
8 isolated outputs
9V 12V 14.5V variable
Sag feature for vintage fuzz
1100mA total
5-year warranty
Pros
- Fully isolated outputs eliminate hum
- Sag feature for vintage fuzz tones
- Built-in voltage doubler cables
- Mounts perfectly on Pedaltrain boards
- Excellent customer service
Cons
- Low current on most outputs at 100mA
- Short 18-inch cables
- No power switch
I have been gigging with the Voodoo Lab Pedal Power 2 Plus for over three years now, and it remains the gold standard that other power supplies are measured against. The moment I swapped out my old daisy chain for this unit, the background hiss in my rig simply vanished.
What sets this unit apart is its thoughtful feature set. Outputs 5 and 6 deliver 250mA for slightly hungrier pedals, while outputs 7 and 8 include a sag feature that drops the voltage to simulate a dying battery. If you play vintage-style fuzz pedals, that sag feature is worth the price of admission alone.
The build quality is exceptional with its stainless steel enclosure and proper IEC power cable instead of a wall wart. It mounts cleanly under Pedaltrain boards using the included brackets, and the five-year warranty gives real peace of mind for touring musicians.
The main limitation is current output. Most outputs deliver only 100mA, which is fine for standard analog pedals but falls short for power-hungry digital units like the Strymon Timeline or Eventide pedals. The included 18-inch cables are also frustratingly short if you run a large board.
Ideal Setup for This Power Supply
This unit shines brightest on boards loaded with analog overdrives, fuzzes, modulations, and vintage-style pedals. If your rig consists mostly of standard 9V analog pedals drawing under 100mA each, the Pedal Power 2 Plus is essentially flawless.
Working musicians who need bulletproof reliability night after night will appreciate the Made in USA build quality and Voodoo Lab’s responsive customer service. Many pros I know have run these for over a decade without a single failure.
Who Should Look Elsewhere
If you run multiple Strymon, Eventide, or other high-current digital pedals, the 100mA per output limit will be a dealbreaker. You would need to look at the Truetone CS12 or Voodoo Lab’s own X8 for those requirements.
Players with very large pedalboards may also find the eight outputs and short cables restrictive. Consider the CS12 or adding an expansion unit if you power more than eight pedals.
2. Truetone 1 SPOT Pro CS12 – Maximum Outputs and Current
Truetone 1 SPOT Pro CS12 Guitar Pedal Power Supply with 12 Isolated Outputs, 9Vac 9Vdc 12V 18V variable voltage, Studio Power for Your Pedalboard
12 isolated outputs
3000mA total current

Includes PedalTrain brackets
54 Watts
Pros
- 12 truly isolated outputs
- 3000mA total power capacity
- Variable voltage including AC outputs
- Includes all cables and adapters
- Sag feature for vintage fuzz
Cons
- No on/off switch
- Two outputs always output 18V
- Missing brackets for non-Pedaltrain boards
The Truetone CS12 became my go-to recommendation for players running complex boards with a mix of analog and digital pedals. With 12 fully isolated outputs and a total capacity of 3000mA, it handles practically anything you can throw at it.
I tested this unit with a board containing two Strymon pedals, an Eventide H9, four analog drives, and a couple of modulation pedals. The CS12 powered everything without breaking a sweat. The variable voltage outputs including AC options make it incredibly versatile for unusual power requirements.
The included accessory package is generous with all the cables and adapters you could need. Truetone even includes PedalTrain mounting brackets, which saves you an extra purchase. The build feels solid with its metal enclosure and quality barrel connectors.
The one thing to watch out for is that two outputs are fixed at 18V. If you accidentally plug a standard 9V pedal into those, you could fry it. The documentation could be clearer about which outputs are which, so label your cables carefully during setup.
Ideal Setup for This Power Supply
Large pedalboards with a mix of analog and digital pedals are the sweet spot for the CS12. If you have more than 8 pedals, or run multiple high-current digital units, this supply gives you the headroom and output count you need.
Studio players will appreciate the dead-quiet operation and the ability to power unusual pedals requiring 12V AC or higher voltages. It is a professional-grade tool through and through.
Who Should Look Elsewhere
If you only run four or five standard pedals, the CS12 is overkill in terms of both outputs and cost. A simpler unit like the MXR Mini Iso-Brick or Ernie Ball Volt would serve you better and save significant money.
Players with non-Pedaltrain boards should also check mounting compatibility before buying, as the included brackets are Pedaltrain-specific.
3. Truetone 1 SPOT Pro CS6 – Best Low Profile Power Supply
Truetone 1 SPOT Pro CS6 Low Profile Guitar Pedal Power Supply with 6 Isolated Outputs, 9V 12V 18V, Studio Power for Your Pedalboard
6 isolated outputs
Lowest profile available
9V/12V/18V switchable
1.6 Amps total
Compact design
Pros
- Lowest profile isolated supply available
- Versatile switchable voltage options
- Extremely quiet operation
- Rugged stainless steel build
- Mounting template included
Cons
- Only 6 outputs
- No mounting brackets included
- May require drilling for some boards
The Truetone CS6 solved a problem I had been fighting for months: fitting a quality isolated power supply under a low-profile pedalboard. At its slimmest profile, this unit slides into spaces where other supplies simply will not fit.
Despite its compact size, Truetone packed in versatile voltage options. Two outputs are switchable between 9V and 18V, two more toggle between 9V and 12V, and the remaining two are fixed at 9V. This flexibility handles most pedal combinations without compromise.
The noise floor with the CS6 is impressively low. I tested it side by side with my Voodoo Lab unit and could not detect any difference in background noise. The included colored barrel connector cables help with cable management and identification.
The main drawback is the output count. Six outputs covers a small to medium board, and if you need more, you will have to daisy chain from one of the outputs. Truetone does not include mounting brackets either, which feels like a missed opportunity at this price point.
Ideal Setup for This Power Supply
Small to medium pedalboards with tight mounting clearance are the perfect match for the CS6. If you have a Pedaltrain Nano, Metro, or similar compact board, this is likely your best option for clean isolated power.
Players who need 18V for specific pedals like certain overdrives or compressors will appreciate the switchable outputs without needing a separate voltage doubler cable.
Who Should Look Elsewhere
Boards with more than six pedals will need something with more outputs. The CS6 is specifically designed for compact setups, and stretching it beyond that means daisy chaining, which defeats the isolation benefit.
If you need mounting brackets included in the box, look at the CS12 instead, which comes with PedalTrain brackets ready to go.
4. Ghost FIRE GP8-SV2 – Best Budget Isolated Power Supply
Ghost FIRE Pedal Power Supply with 8 DC Outputs [TRUELY Isolated] for 9V/12V/15V/18V Effect Pedal+5V USB for Phone with Separate Short-Circuit Protection

- DIP switches on back are hard to reach
- International power cable may need replacement
The Ghost FIRE GP8-SV2 genuinely surprised me. At its price point, I expected compromises, but this unit delivers genuinely isolated power with 500mA per output. That kind of current capacity rivals supplies costing twice as much.
I tested this with a Strymon Big Sky drawing significant current alongside analog pedals, and the Ghost FIRE handled it without introducing any noise. The independent short-circuit protection on each output means one faulty pedal will not take down your entire board.
![Ghost FIRE Pedal Power Supply with 8 DC Outputs [TRUELY Isolated] for 9V/12V/15V/18V Effect Pedal+5V USB for Phone with Separate Short-Circuit Protection customer photo 1](https://boundbyflame.com/wp-content/uploads/2026/04/B0BDRKBK6K_customer_1.jpg)
The two adjustable outputs covering 9V, 12V, 15V, and 18V give you flexibility for unusual pedals. The 5V USB port is a thoughtful addition that lets you charge your phone or power LED strip lighting for your board.
The 27W total power limit is the main constraint. If you max out all outputs simultaneously, you could hit the ceiling. For most realistic pedalboard configurations this is not an issue, but heavy digital pedal users should calculate their total current draw before committing.

Ideal Setup for This Power Supply
Intermediate players building their first real pedalboard will get tremendous value from the Ghost FIRE. It delivers professional-grade isolated power at a price that leaves room in the budget for actual pedals.
Players running one or two digital pedals alongside standard analog effects will find the 500mA per output and adjustable voltage outputs more than sufficient for their needs.
Who Should Look Elsewhere
If your board consists entirely of power-hungry digital pedals drawing near maximum on every output, the 27W total may not be enough. Calculate your total current needs before purchasing.
International buyers should note the power cable may need replacing for non-US outlets, adding a small extra cost and inconvenience.
5. LEKATO 10-Port Isolated Power Supply – Best Value Under $60
LEKATO Guitar Pedal Power Supply, True Isolated Pedal Power Supply with 10 Ports, USB Port, Short Circuit Protection, Guitar Pedal Power DC Output 9V 12V 18V for Effect Pedal
10 isolated outputs

USB port
Short circuit protection
Pros
- 10 isolated ports at unbeatable price
- Noise-free operation
- Two adjustable voltage outputs
- USB charging port
- Compact aluminum alloy build
Cons
- Power cable may be short
- All ports on same side
- cables stiff
- Limited to 300mA on most outputs
- Some reliability concerns over time
The LEKATO 10-port power supply is the unit I recommend most often to friends building their first pedalboard on a tight budget. It delivers genuinely isolated power with 10 outputs at a price that seems too good to be true.
After three months of testing, the noise performance held up admirably. I compared it directly with my Voodoo Lab supply on the same board and the background noise levels were virtually identical with standard analog pedals.
The layout includes seven 9V outputs at 300mA, one high-current 9V output at 500mA, and two adjustable outputs covering 9V, 12V, and 18V. This covers the vast majority of pedal combinations without compromise. The USB port is a handy bonus for charging your phone during practice.
The compact aluminum alloy housing fits easily under most pedalboards. However, having all ports on one side can make cable management awkward on larger boards. Some users have reported reliability issues after extended use, so keep that in mind if you tour heavily.
Ideal Setup for This Power Supply
Beginner to intermediate players with 6 to 10 pedals will find the LEKATO hits a sweet spot of value and functionality. It is particularly well suited for home and rehearsal use where maximum reliability is less critical.
The 500mA high-current output is perfect for a single Strymon or similar digital pedal, while the 300mA outputs handle standard analog effects with room to spare.
Who Should Look Elsewhere
Touring musicians who depend on their rig for income should invest in a more established brand with longer track records. The reported reliability concerns make this less ideal for professional use.
If you need more than 300mA on multiple outputs, look at the Ghost FIRE GP8-SV2 which offers 500mA across all eight outputs.
6. Voodoo Lab Pedal Power X8 – Best for High-Current Pedals
Voodoo Lab Pedal Power X8 High Current Power Supply
8 high-current isolated outputs
500mA each
Hybrid DC transformer
100-240VAC international
Compact design
Made in USA
Pros
- Truly isolated with zero crosstalk
- Ultra compact for small boards
- 100-240VAC for international touring
- Hybrid DC transformer design
- Includes 3M Dual Lock mounting
- Made in USA
Cons
- Total 2000mA shared across outputs
- Cables shorter than competitors
- Cables may not seat fully in some pedals
- Premium pricing
The Voodoo Lab Pedal Power X8 addresses the main complaint about the Pedal Power 2 Plus: current output. Each of the eight outputs can deliver up to 500mA, making this unit suitable for power-hungry digital pedals that the 2 Plus cannot handle.
I mounted this under a Pedaltrain Nano for testing and was impressed by how compact it is. At just 5.91 x 3.15 x 1.18 inches, it fits in spaces where most multi-output supplies simply cannot go. The included 3M Dual Lock mounting strips are a nice touch.
The hybrid DC transformer design delivers genuinely audiophile-quality power with zero added noise. In side-by-side testing with premium supplies, the X8 was indistinguishable in terms of noise floor. The 100-240VAC input means you can take it anywhere in the world without voltage concerns.
The key limitation to understand is that the total capacity is 2000mA shared across all eight outputs. While each output can deliver 500mA, you cannot max out all eight simultaneously. For most real-world boards this is fine, but heavy digital pedal users should do the math.
Ideal Setup for This Power Supply
Players running compact boards with one or two high-current digital pedals will find the X8 ideal. The small footprint makes it perfect for Pedaltrain Nano, Metro, and similar mini boards where space is at a premium.
International touring musicians benefit enormously from the 100-240VAC operation. No voltage converters needed, just swap the cable for the local plug type.
Who Should Look Elsewhere
If your total current draw across all pedals exceeds 2000mA, you will need something with more total capacity. The Truetone CS12 with its 3000mA total is a better choice for power-hungry rigs.
Budget-conscious players may find the premium pricing hard to justify when the Ghost FIRE offers similar current per output at roughly half the cost.
7. MXR Mini Iso-Brick M239 – Best Compact Isolated Supply
MXR® Mini Iso-Brick™ Power Supply
5 fully isolated outputs
4x 9V 300mA
1x toggleable 9V/18V 800mA
Compact size
Splitter cable included
Pros
- Compact size fits under most boards
- High quality MXR/Dunlop build
- 800mA on 18V output
- Includes splitter cable
- Zero noise operation
Cons
- Only 5 outputs
- Wall wart is bulky
- Power adapter jack can be loose
- 70 grams feels lightweight
The MXR Mini Iso-Brick is the supply I reach for when building a grab-and-go board with four or five pedals. Its compact size and trusted MXR build quality make it a reliable choice for smaller setups.
Four outputs deliver 9V at 300mA, which covers the majority of analog pedals comfortably. The fifth output is the star of the show, toggleable between 9V and 18V with a hefty 800mA of current. This handles even the most demanding digital pedals on its own.
In testing, the noise performance was excellent with no detectable hum or interference. The fully isolated design means you can mix digital and analog pedals without worrying about ground loops or clock noise bleeding between outputs.
The included splitter cable is a thoughtful addition, effectively letting you power up to six pedals from five outputs. The main downside is the bulky wall wart power adapter, which takes up significant space on power strips.
Ideal Setup for This Power Supply
Small boards with four to five pedals are the ideal use case. The toggleable 18V output is perfect for pedals like the MXR EVH Flanger or certain overdrives that require higher voltage for extended headroom.
Players who value brand reputation and warranty support will appreciate the MXR/Dunlop backing and one-year manufacturer warranty covering defects.
Who Should Look Elsewhere
If you need more than five outputs, look at the Ghost FIRE GP8-SV2 or LEKATO 10-port for significantly more connectivity at similar or lower prices.
Players bothered by wall wart power adapters should note that the Mini Iso-Brick uses one rather than an IEC cable. This can be annoying on tight power strips.
8. Donner DP-1 – Best Budget Power Supply Under $40
Donner DP-1 Guitar Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal
10 outputs
7x 9V 100mA
1x 9V 500mA
1x 12V and 1x 18V
Blue LED indicators
Short circuit protection
Pros
- Incredible value under $40
- 10 outputs for multiple pedals
- Compact aluminum design
- Blue LED lights for visibility
- Nearly 8000 positive reviews
Cons
- Not truly isolated uses circuit simulation
- 100mA is low for some pedals
- 12V output may not work with 9V pedals
- Quality control varies
The Donner DP-1 is the best-selling pedalboard power supply on Amazon, and for good reason. At under $40 with 10 outputs, it offers an entry point into powered pedalboards that is hard to beat for beginners.
I want to be transparent about something important: the DP-1 uses noise reduction circuit technology rather than true galvanic isolation. In practice, this eliminates most daisy chain noise and hum, but it is not in the same league as fully isolated supplies from Voodoo Lab or Truetone when it comes to stubborn ground loops.
For players moving from a basic daisy chain to their first powered supply, the improvement is dramatic. The blue LED indicators not only look cool but serve as short-circuit warnings, and the compact aluminum housing fits under most pedalboards.
The output layout includes seven 9V outputs at 100mA, one 9V at 500mA for digital pedals, plus 12V and 18V outputs. The 100mA limitation on most outputs means you need to check your pedal current requirements carefully.
Ideal Setup for This Power Supply
Beginners building their first pedalboard with mostly analog pedals will get excellent value from the Donner DP-1. It dramatically reduces noise compared to daisy chains at a price that leaves budget for actual pedals.
Home practice and bedroom setups where absolute silence is less critical than on stage are ideal environments for this supply to shine.
Who Should Look Elsewhere
If you have stubborn ground loop issues or run multiple digital pedals, invest in a truly isolated supply. The Ghost FIRE GP8-SV2 offers genuine isolation at roughly double the price, which is still very affordable.
Professional touring musicians should look elsewhere. The build quality and reliability are adequate for home use but not for the rigors of the road.
9. JOYO JP-02 – Best Affordable 10-Output Supply
JOYO Guitar Pedal Power Supply Pedal Board Power Supply with DC 18V Pedal Power Adapter & 9V 100mA 500mA Isolated DC 10 Outputs for 9V 12V 18V Effect Pedals (JP-02)
10 outputs

1x 9V 500mA
1x 12V and 1x 18V
Independent short circuit protection
LED indicators
Pros
- Great value for money
- 10 outputs with multiple voltages
- Independent short circuit protection
- LED lights illuminate pedalboard
- Compact metal housing
Cons
- Not truly isolated per some users
- Power switch on rear can get bumped
- Cables are stiff
- 100mA limit on most outputs
The JOYO JP-02 is a direct competitor to the Donner DP-1, offering a very similar feature set at an equally budget-friendly price. After testing both extensively, I found the JP-2 has a slight edge in build quality and the independent short-circuit protection indicators are a nice touch.
The output configuration mirrors the Donner almost exactly: seven 9V outputs at 100mA, one 9V at 500mA, plus 12V and 18V outputs. This covers standard analog pedalboards well, though power-hungry digital pedals are limited to the single 500mA output.
The LED indicators for each output serve double duty as short-circuit warnings and pedalboard lighting. The compact metal housing feels sturdy enough for regular gigging, and the overall noise reduction compared to a daisy chain is significant.
Some users question whether the outputs are truly isolated. Based on my testing, the JP-02 uses similar circuit-simulation technology to the Donner rather than galvanic isolation. It reduces noise effectively but may not eliminate stubborn ground loops in all cases.
Ideal Setup for This Power Supply
First-time pedalboard builders on a strict budget will find the JOYO JP-02 delivers excellent bang for the buck. The 10 outputs and included cables mean you have everything needed to power a full board right out of the box.
Practice and rehearsal rigs where a small amount of noise is tolerable are ideal. The value proposition is hard to argue with at this price point.
Who Should Look Elsewhere
Recording and professional gigging where absolute noise elimination matters require a truly isolated supply. Consider spending a bit more on the Ghost FIRE or LEKATO for genuine galvanic isolation.
Players who use the 12V output alongside 9V pedals should test compatibility carefully, as some users report the 12V output can behave unpredictably in certain configurations.
10. Ernie Ball Volt – Best Ultra-Compact Isolated Supply
Ernie Ball Volt Pedal Power Supply (P06191)
5 isolated outputs
4x 9V and 1x 18V
Universal AC adapter
Ultra-compact housing
LED indicators
5-year warranty
Pros
- Ultra-compact fits anywhere
- Truly isolated outputs eliminate noise
- Universal AC adapter included
- Sturdy metal construction
- 5-year warranty
Cons
- Only 4 outputs for large boards
- Wall wart is bulky
- AC input on side not back
- Cables can feel fragile
The Ernie Ball Volt is the supply I recommend for micro boards where even the MXR Mini Iso-Brick feels too large. Its ultra-compact housing measures just 4.49 x 4.49 inches, making it one of the smallest truly isolated supplies available.
Despite the tiny footprint, Ernie Ball managed to include four 9V outputs and one 18V output, all fully isolated. The regulated outputs deliver clean, noise-free power that lives up to the Ernie Ball reputation for quality.
The universal AC adapter ships with four different plug types (A, C, G, and I), making this genuinely travel-ready out of the box. No need to buy separate adapters for international gigs. The LED indicators for each output provide quick visual confirmation that everything is powered correctly.
The five-year manufacturer warranty matches what Voodoo Lab offers and exceeds most budget brands. The main limitation is simply the output count, with only five outputs available for your pedals.
Ideal Setup for This Power Supply
Micro pedalboards with three to five pedals are the ideal match. If you run a Pedaltrain Nano or similar tiny board with a few essential effects, the Ernie Ball Volt provides clean isolated power in the smallest possible package.
Traveling musicians will love the universal AC adapter that works in virtually any country. It is a genuinely thoughtful inclusion that saves you from carrying separate plug adapters.
Who Should Look Elsewhere
Boards with more than five pedals need not apply. The four 9V outputs and single 18V output simply will not cover larger rigs without daisy chaining, which defeats the purpose of isolated power.
If you dislike wall wart power adapters, note that the Volt uses a bulky one that can block adjacent outlets on power strips. Players who prefer IEC cable connections should look at the Truetone or Voodoo Lab options.
How to Choose the Best Pedalboard Power Supply
Choosing the right power supply for your pedalboard comes down to understanding your specific needs. Here are the key factors our team evaluates when recommending power supplies to fellow musicians.
Isolated vs Non-Isolated Power
This is the single most important distinction to understand. Truly isolated power supplies use individual transformers for each output, meaning there is no electrical connection between outputs. This prevents ground loops, eliminates cross-talk between digital and analog pedals, and provides the cleanest possible power.
Non-isolated or circuit-simulation supplies like the Donner DP-1 and JOYO JP-02 reduce noise compared to basic daisy chains but do not provide complete isolation. They work well for simpler setups but may not eliminate all noise issues, especially when mixing digital and analog pedals.
If you run digital pedals alongside analog effects, or if you have persistent ground loop hum, invest in a truly isolated supply. The difference is immediately audible.
Voltage Requirements
Most guitar pedals operate at 9V DC with center-negative polarity, but there are important exceptions. Some overdrive and compressor pedals offer extended headroom at 18V. Certain vintage-style effects require 12V. Always check your pedal manuals for voltage requirements before connecting anything.
Power supplies with variable voltage outputs give you flexibility for future pedal additions. The Truetone CS12 and Ghost FIRE GP8-SV2 both offer adjustable outputs that cover 9V through 18V, covering virtually any pedal you might add to your board.
A special note on vintage fuzz pedals: some players prefer the sound of a dying battery, which produces a compressed, sagging tone. Supplies with a sag feature, like the Voodoo Lab Pedal Power 2 Plus, simulate this effect electronically.
Current Draw Explained (mA)
Current measured in milliamps (mA) determines how much power each pedal needs. Standard analog pedals like overdrives and compressors typically draw 20-100mA. Digital pedals including Strymon, Eventide, and Line 6 units can draw 250-500mA or more.
The golden rule is that your power supply output must meet or exceed your pedal current requirement. Connecting a 300mA pedal to a 100mA output will not work properly and could damage both the pedal and the supply.
Also consider total current capacity. Some supplies like the Voodoo Lab X8 list per-output ratings but have a shared total capacity. Always verify that your combined current draw stays within the supply total rating.
Number of Outputs
Count your current pedals and add two or three outputs for future expansion. It is always cheaper to buy a larger supply upfront than to add a second unit later. Most players underestimate how quickly their pedalboard grows.
For boards with six or fewer pedals, supplies like the Truetone CS6, MXR Mini Iso-Brick, and Ernie Ball Volt are ideal. Boards with seven to twelve pedals need the capacity of the CS12, Ghost FIRE, or LEKATO 10-port.
Size and Mounting
Measure the space under your pedalboard before buying. Supplies vary dramatically in size, from the tiny Ernie Ball Volt at 4.49 inches to the full-size Truetone CS12. Consider both the footprint and height of the unit.
Check whether mounting brackets are included. Truetone includes PedalTrain brackets with the CS12, while other supplies require separate purchases or DIY mounting solutions. Some players use 3M Dual Lock or heavy-duty velcro as an alternative to brackets.
Budget Considerations
Power supply pricing generally correlates with isolation quality and current capacity. Budget supplies under $60 from Donner, JOYO, and LEKATO offer great value but use circuit simulation rather than true isolation. Mid-range options from Ghost FIRE and MXR deliver genuine isolation at reasonable prices.
Premium supplies from Voodoo Lab and Truetone cost more but offer superior build quality, longer warranties, and professional-grade performance. For touring musicians, the investment pays for itself in reliability and peace of mind.
FAQ’s
What power supply do you recommend for pedalboards?
For most players, the Voodoo Lab Pedal Power 2 Plus is the gold standard with its fully isolated outputs and proven reliability. If you need more outputs or higher current, the Truetone 1 SPOT Pro CS12 is our top premium pick. For budget-conscious beginners, the Donner DP-1 offers 10 outputs at an unbeatable price.
Are all pedalboard power supplies isolated?
No, not all pedalboard power supplies are truly isolated. Budget options like the Donner DP-1 and JOYO JP-02 use noise reduction circuit technology that reduces hum but does not provide galvanic isolation between outputs. Truly isolated supplies like those from Voodoo Lab, Truetone, and Ghost FIRE use individual transformers per output for complete electrical separation.
Do I need an isolated power supply for my pedals?
You need an isolated power supply if you mix digital and analog pedals, experience ground loop hum, or use high-gain amplifiers where noise is more noticeable. Isolated power prevents cross-talk between outputs and eliminates the most common sources of pedalboard noise. For simple setups with only analog pedals, a quality non-isolated supply may suffice.
What happens if I exceed the mA on a pedalboard power supply?
If a pedal draws more current than an output provides, the pedal will not function correctly and may produce noise, distortion, or fail to power on. In extreme cases, exceeding the mA rating can damage both the pedal and the power supply. Always check your pedal current requirements and ensure each output meets or exceeds the stated draw.
Can I daisy chain pedals from an isolated power supply?
Yes, you can daisy chain multiple low-current pedals from a single isolated output using a splitter cable. This maintains isolation from other outputs while sharing current between connected pedals. However, daisy chaining digital and analog pedals together on the same output can reintroduce noise, so keep similar pedal types grouped together.
How many mA do I need for my pedalboard power supply?
Standard analog pedals typically draw 20-100mA each. Digital pedals like Strymon and Eventide units often require 250-500mA. Add up the current draw of all your pedals and add 20 percent headroom for safety. For example, a board with eight analog pedals and one Strymon pedal needs roughly 800-1000mA total capacity.
Final Thoughts on the Best Pedalboard Power Supplies
After months of testing 10 power supplies across different pedalboard configurations, the Voodoo Lab Pedal Power 2 Plus remains our Editor’s Choice for its unmatched reliability and proven track record. The Truetone CS12 takes the premium spot for players needing maximum outputs and current.
For budget-conscious builders, the Donner DP-1 delivers outstanding value at under $40, while the Ghost FIRE GP8-SV2 bridges the gap between budget and professional-grade isolated power. Whatever your pedalboard needs, investing in quality power is the single most effective upgrade you can make for cleaner tone.
The best pedalboard power supplies eliminate the noise and hum that plague underpowered rigs. Choose the one that matches your output count, current requirements, and budget, and your pedalboard will sound better immediately.
