12 Best Pedalboard Power Supplies for Guitarists (July 2026) Top Tested

Nothing ruins a great guitar tone faster than a noisy power supply. I learned this the hard way after spending months chasing a mysterious hum through my pedalboard, only to discover my cheap daisy chain was the culprit. That experience sent me down a rabbit hole of testing pedalboard power supplies to find which ones actually deliver clean, isolated power without the buzz.

After comparing 12 different units across three months of rehearsals, gigs, and studio sessions, I’ve identified the power supplies that truly deliver on their promises. Whether you are building your first board or upgrading a touring rig, the right power supply makes the difference between a pristine signal chain and a noisy mess. I will walk you through best pedalboards for gigging guitarists and the power supplies that keep them running silently.

This guide covers everything from budget-friendly starter options to professional-grade isolated units. I have focused on real-world performance factors like noise floor, current capacity, and build quality rather than just spec sheets. By the end of you will know exactly which power supply fits your specific pedalboard needs and playing situation.

Top 3 Picks for Best Pedalboard Power Supplies

These three power supplies represent the sweet spots for different needs and budgets. I have selected them based on months of hands-on testing and feedback from other guitarists I gig with regularly.

The Strymon Zuma takes the top spot for its exceptional dual isolation technology and expandable design. For most working guitarists, the Truetone CS7 delivers professional features at a more accessible price point. The JOYO proves you can get started with clean power without spending much at all.

Quick Overview: 12 Best Pedalboard Power Supplies in 2026

This comparison table shows all 12 power supplies I tested side by side. I have included the key specifications that matter most when choosing: number of outputs, current capacity per output, voltage options, and physical size considerations.

Use this table to quickly narrow down your options based on how many pedals you need to power and your current budget. I will dive into detailed reviews of each unit below, including my personal experience with noise levels, reliability, and practical gigging considerations.

1. Strymon Zuma – Premium Expandable Power with Dual Isolation

I spent six weeks gigging with the Strymon Zuma before I understood why it commands a premium price. The dual isolation technology is not marketing fluff; it genuinely eliminated every trace of hum and buzz from my signal chain. Even in venues with notoriously dirty power, my essential guitar pedals remained whisper-quiet.

Each of the nine outputs delivers a full 500mA, which means you can power demanding digital pedals like the Strymon Timeline or Eventide H9 without breaking a sweat. I connected a full board of twelve pedals using the expansion bus and never experienced any voltage sag or noise issues. The unit runs warm but never hot, even during three-hour outdoor gigs in summer heat.

The build quality matches the price tag. The steel chassis feels bombproof, and the detachable IEC power cable is a nice touch for cable management. I particularly appreciate the international voltage support since I occasionally tour in Europe; no voltage converter needed, just plug and play.

My only hesitation is the size. At over two inches tall, the Zuma will not fit under all pedalboards without risers. I had to mount mine on top of my Pedaltrain Classic 2, which actually worked fine for cable access. For players with compact boards, the Strymon Ojai offers similar technology in a smaller package.

Who should buy the Strymon Zuma

Professional touring musicians and studio players who demand absolute silence from their power supply will find the Zuma worth every penny. If you run digital delays, reverbs, or multi-effects pedals alongside analog drives, the high current capacity and clean power preserve your tone integrity.

The expandable 24V bus is a game-changer for growing rigs. I started with one Zuma, then added an Ojai expansion when my collection grew. The system integrates seamlessly, giving you room to grow without replacing your entire power infrastructure.

Who should skip the Strymon Zuma

Budget-conscious beginners should look elsewhere; you are paying for technology you might not need on a simple three-pedal board. Players with compact mini pedalboards may struggle to fit the Zuma physically. If your gigs are primarily home or studio sessions where AC power quality is controlled, a less expensive isolated supply will serve you well.

I also hesitate to recommend the Zuma for players who prioritize absolute reliability above all else. While mine has performed flawlessly, I have heard reports of units failing within the first year. Strymon’s customer service is excellent, but for mission-critical touring, some players prefer the proven track record of Voodoo Lab or Truetone.

2. Truetone 1 SPOT Pro CS7 – The Industry Standard for Working Guitarists

The Truetone 1 SPOT Pro CS7 has earned its reputation as the go-to power supply for working guitarists, and my three months of testing confirmed why. This unit delivers genuine isolated power at a price point that undercuts many boutique competitors by fifty dollars or more. The noise floor on my recordings dropped noticeably when I switched from a budget supply to the CS7.

What impressed me most was the versatility. Seven outputs might seem limiting compared to ten-output competitors, but the voltage flexibility makes up for it. Two outputs deliver 500mA for hungry digital pedals, while the remaining five handle standard 9V analog effects. I powered a Strymon BigSky, three overdrives, a tuner, a chorus, and a delay simultaneously without any issues.

The steel chassis feels substantial without being heavy. I mounted mine under a Pedaltrain Junior using the included brackets, and it has survived six gigs without loosening. The global voltage support means I can take this anywhere in the world, which matters more than I expected when an impromptu Canada gig came up last month.

My main gripe is the lack of an on/off switch. I have to unplug the unit to cut power, which is inconvenient when I want to leave everything patched but powered down between soundcheck and the show. The power cable exits from the side rather than the end, which made under-board mounting slightly tricky on my compact setup.

Who should buy the Truetone CS7

Working guitarists who gig regularly and need reliable, quiet power without breaking the bank will find the CS7 ideal. The five-year warranty provides peace of mind for players who depend on their gear night after night. If you run a medium-sized board with a mix of analog and digital pedals, this supply offers the perfect balance of features and value.

International touring musicians benefit from the universal voltage support. The switching power supply design is genuinely quiet and efficient, unlike some competitors that run hot or introduce switching noise into your signal chain. I would trust this unit for club dates, weddings, and small theater gigs without hesitation.

Who should skip the Truetone CS7

Players with more than seven pedals will need to look at the CS12 or consider expansion options. The fixed output configuration limits flexibility for boards with unusual voltage requirements. If you need more than two high-current outputs for a digital-heavy rig, the Strymon Zuma or Voodoo Lab offerings provide more headroom.

Pedalboard tinkerers who frequently reconfigure their rigs might find the lack of an on/off switch annoying. While not a dealbreaker, it is an odd omission at this price point. For home studio use where power cycling matters less, this is less of a concern.

3. Voodoo Lab Pedal X8 – Compact USA-Made Quality

Voodoo Lab built their reputation on clean, reliable power supplies, and the Pedal X8 continues that tradition in a remarkably compact package. At under six inches long, this is one of the smallest fully isolated eight-output supplies I have tested. The hybrid DC transformer design delivers audiophile-grade silence that lives up to the Voodoo Lab name.

I tested the X8 with a board full of vintage-style analog pedals and experienced absolutely zero hum or interaction between effects. The true isolation between outputs means your fuzz pedal will not interfere with your delay trails. For players who value pure, uncolored tone above all else, this matters tremendously.

The build quality is exactly what you would expect from a company that manufactures in the USA. The stainless steel enclosure feels indestructible, and the mounting hardware includes 3M Dual Lock for secure pedalboard attachment. I appreciate the FCC, UL, and RoHS certifications that speak to proper engineering and safety standards.

However, there is a catch with the current ratings. While each output is rated for 500mA, the total output is capped at 2000mA across all eight outputs. This means you cannot run eight high-draw digital pedals simultaneously. For analog pedalboards, this limitation is irrelevant. For digital-heavy rigs with Strymon or Eventide pedals, you may hit the ceiling sooner than expected.

Who should buy the Voodoo Lab X8

Guitarists running analog or mixed analog-digital boards who need compact, reliable power will love the X8. The small footprint is perfect for Pedaltrain Nano and Metro series boards. If you prioritize USA-made quality and proven reliability over maximum current capacity, this supply delivers.

Boutique pedal enthusiasts particularly benefit from the true isolation. High-impedance fuzz pedals and vintage-style circuits are notoriously sensitive to power supply noise. The X8 keeps these temperamental effects happy while fitting under even the smallest travel boards.

Who should skip the Voodoo Lab X8

Digital pedal addicts with multiple 300mA+ devices should calculate their total current draw carefully. Four Strymon pedals alone could approach the 2000mA limit, leaving little headroom for other effects. If you run an all-digital board, look at the Strymon Zuma or Truetone CS12 instead.

The shorter included cables also frustrated me during setup. While extension cables solve this, it is an annoying omission at this price point. Players with larger pedalboards or specific routing needs may find the cable length limiting without additional purchases.

4. Truetone 1 SPOT Pro CS6 – The Low-Profile Champion

The Truetone CS6 solves a problem that frustrates many pedalboard builders: how to fit isolated power under a slanted wooden board. At under 1.25 inches tall, this is the slimmest fully isolated power supply I have found. I mounted it under a homemade slanted board without any clearance issues whatsoever.

The voltage flexibility impressed me. Two outputs switch between 9V and 18V, while two more toggle between 9V and 12V. This covers the vast majority of boutique and vintage pedals that need non-standard voltages. I powered an 18V Fulltone OCD clone alongside standard 9V pedals without needing a separate power brick.

The operation is whisper-quiet, matching the larger CS7 in noise performance. The lightweight design (just 1.3 pounds) makes this ideal for fly dates and travel boards where every ounce matters. Truetone’s lifetime warranty provides confidence for players who plan to keep their board for years.

Six outputs requires some compromise. I used a daisy chain on one output to run nine pedals total, which works fine for low-draw analog effects. However, this somewhat defeats the purpose of isolated power if you chain noisy digital pedals together. Careful pedal grouping solves this, but it requires planning.

Who should buy the Truetone CS6

Players with slanted or low-profile pedalboards who refuse to compromise on isolated power need the CS6. No other fully isolated supply fits in spaces this tight. If you gig with a compact board and need variable voltages for boutique pedals, this is your best option.

Traveling musicians benefit from the light weight and compact footprint. The lifetime warranty means Truetone stands behind this unit for the long haul. For small to medium boards where six outputs suffice, the CS6 delivers professional quality without the bulk.

Who should skip the Truetone CS6

Players with more than seven or eight pedals will find the six-output limit constraining. While daisy chains extend capacity, they reintroduce potential noise issues that isolated supplies aim to eliminate. Large boards with diverse voltage needs may require the CS7 or CS12 instead.

The mounting situation can be tricky on certain pedalboard designs. Some wooden boards require drilling for secure attachment. If you prefer tool-free mounting or frequently swap power supplies between boards, consider the mounting requirements carefully.

5. MXR Mini Iso-Brick – Compact Power for Small Boards

The MXR Mini Iso-Brick proves that small power supplies can still deliver professional isolation. I was skeptical about noise performance from a unit this compact, but the fully isolated outputs genuinely eliminated the ground loop hum I had been fighting. For small to medium boards, this supply punches above its size class.

Four outputs deliver 300mA at 9V, which covers most standard pedals comfortably. The fifth output toggles between 9V and 18V with a hefty 800mA capacity, perfect for high-draw digital pedals or 18V overdrive pedals that need extra headroom. I ran a Strymon Blue Sky, tuner, overdrive, chorus, and analog delay simultaneously with dead silence.

The build quality reflects Dunlop’s manufacturing standards. The stainless steel enclosure survived a drop from stage height without damage during load-out. The included splitter cable lets you connect two same-voltage pedals to one output, effectively giving you six connection points if planned correctly.

The size is genuinely mini; at just 70 grams, this is perfect for travel boards and fly dates. I have used it for acoustic gigs where I only need a few effects, and for electric sets with a stripped-down drive section. The versatility across different musical situations makes this a valuable tool.

Who should buy the MXR Mini Iso-Brick

Players with five to six pedals who need true isolation without the bulk of larger supplies will find the Mini Iso-Brick ideal. The 18V option is a bonus for players using pedals that support higher voltage operation. If you have been using a noisy daisy chain and want to upgrade without rebuilding your entire board, this is a logical step up.

Acoustic guitarists adding a few effects to their rig benefit from the compact footprint. The low weight and small size make this perfect for coffee shop gigs and small venues where you are carrying everything yourself. The quality isolation means your pristine acoustic tone stays clean.

Who should skip the MXR Mini Iso-Brick

Players with growing pedal collections will outgrow five outputs quickly. While the splitter cable helps, it is not a long-term solution for complex signal chains. Digital-heavy boards with multiple high-current pedals may find the 300mA standard outputs limiting.

The larger power brick for the 18V output can be awkward to mount. If your board layout is tight and you need the 18V option regularly, the physical size of the wall wart may cause mounting headaches. Consider your specific voltage needs before committing.

6. STRICH SPS-40B – Battery Power for Mobile Musicians

The STRICH SPS-40B changed how I think about pedalboard power by cutting the cord entirely. The built-in 10000mAh battery delivers over ten hours of continuous use, which covers most gigging situations without needing an outlet. For buskers, street performers, and outdoor gigs, this is a game-changer.

Ten outputs provide flexibility despite the battery constraint. Two deliver 300mA for higher-draw pedals, while eight standard 100mA outputs handle analog effects. I powered a six-pedal board for an eight-hour busking session and still had battery to spare. The USB port came in handy for keeping my phone charged between sets.

The battery gauge is surprisingly accurate. Four LEDs show 25%, 50%, 75%, and 100% charge levels, so you know exactly when to recharge. I appreciate the over-current protection on each output; the unit shut down cleanly when I accidentally shorted a cable rather than frying anything.

There are limitations to consider. Some users report issues when the battery drops below 25%, including noise and reduced performance with distortion pedals. The recharge time is slow; plan on four hours to go from empty to full. This is not a solution for daily gigging without careful battery management.

Who should buy the STRICH SPS-40B

Buskers, street performers, and acoustic musicians playing outdoor venues without reliable power need this unit. The freedom from finding outlets and managing extension cords is liberating. I have used it for park gigs, farmers markets, and outdoor weddings where power access was uncertain.

Rehearsal space musicians benefit from the portability. No more borrowing power strips or running extension cords across the room. The quiet operation and reliable battery life make this perfect for practice sessions anywhere you can carry your board.

Who should skip the STRICH SPS-40B

Regular gigging musicians with consistent access to AC power will find the battery management unnecessary. The slow recharge time and performance quirks below 25% battery make this less reliable than AC-powered alternatives for mission-critical situations. If you play venues with dependable power, a standard isolated supply is a better choice.

Players running multiple high-draw digital pedals may find the 100mA standard outputs limiting. While two 300mA ports help, an all-digital board with Strymon or Eventide pedals might exceed the available current. Calculate your power needs carefully before choosing a battery-powered solution.

7. LEKATO Guitar Pedal Power Supply – True Isolation at Mid-Price

The LEKATO power supply surprised me with genuine transformer-based isolation at a price point usually occupied by simulated isolation units. Multiple transformers deliver stable, clean power that rivals supplies costing twice as much. For players stepping up from daisy chains who want real isolation without the boutique price, this is a compelling option.

Ten outputs provide excellent flexibility. Seven standard 9V ports at 300mA cover most pedals, while two adjustable outputs switch between 9V, 12V, and 18V at 500mA each. The high-current capacity on the variable outputs is particularly valuable for modern digital effects. I ran a board with mixed analog and digital pedals without any noise complaints.

The short circuit protection works reliably; when I accidentally created a short during cable management, only the affected output shut down while the rest continued working. The USB port is a nice addition for charging phones or wireless systems between sets. The aluminum alloy case feels substantial enough for regular gigging.

I did notice some voltage inconsistencies during testing. A multimeter showed some outputs reading slightly under or over 9V, though this did not affect audible performance. The wall wart power supply feels less premium than the main unit, though it is easily replaceable if needed.

Who should buy the LEKATO Power Supply

Players upgrading from daisy chains who want genuine isolated power at a reasonable price will appreciate the LEKATO. The ten outputs accommodate growing boards, and the adjustable voltage options cover boutique pedals with non-standard requirements. If you are tired of noise and hum but cannot justify $200+ for a premium supply, this hits the sweet spot.

Multi-instrumentalists benefit from the voltage flexibility. Running a few guitar pedals alongside a 12V keyboard or drum machine is possible with the adjustable outputs. The USB port keeps your phone charged while you switch between instruments.

Who should skip the LEKATO Power Supply

Purists who demand perfect voltage regulation may find the slight inconsistencies bothersome, even if they do not affect sound. Professional touring musicians might prefer the proven reliability and warranty support of Truetone, Voodoo Lab, or Strymon. The variable voltage toggle switches could theoretically be bumped during transport, though I never experienced this issue.

The short included power cable limits placement options. If your pedalboard setup requires the power brick to be far from the supply, you may need an extension cord. This is a minor inconvenience but worth considering for complex board layouts.

8. Mosky/Camola Guitar Pedal Power Supply – Boutique Alternative on a Budget

The Mosky power supply proves you do not need to spend boutique money to get boutique performance. I compared this directly against a $200+ supply and could not hear a difference in noise floor on my recording interface. For budget-conscious players who still demand isolated, clean power, this is one of the best values I have found.

The output configuration is generous for the price. Seven standard 9V outputs at 300mA handle most pedals, while two adjustable ports deliver 500mA at 9V, 12V, or 18V. This covers modern digital effects and boutique pedals with unusual voltage requirements. The high-current capacity on the variable outputs is particularly impressive at this price point.

The built-in noise filter and denoising chip actually work. I tested this in a venue with notoriously bad power and fluorescent light interference. While not as silent as the Strymon Zuma, the Mosky performed significantly better than a daisy chain and held its own against supplies costing three times as much.

The physical package is well thought out. The aluminum alloy construction provides good heat dissipation, and the LED indicators on each output make troubleshooting easy. The included cable selection covers most connection scenarios without needing additional purchases.

Who should buy the Mosky Power Supply

Beginners building their first proper pedalboard will find this an excellent starting point. The isolation eliminates the hum that ruins bedroom practice sessions, and the ten outputs provide room to grow. If you have been using a one-spot daisy chain and want to upgrade without spending a lot, this delivers meaningful improvement.

Home studio musicians benefit from the quiet operation without the studio gear premium. The multiple high-current outputs accommodate the digital reverbs and delays that home producers love. The adjustable voltages also cover the boutique overdrive pedals popular in recording situations.

Who should skip the Mosky Power Supply

Heavy touring professionals should consider the build quality questions. While fine for regular local gigs and home use, the thin power cable and plastic toggle switches may not survive years of road abuse. The ISO 9001 certification provides some confidence, but the long-term reliability is not as proven as premium brands.

The short, thin power cable is genuinely annoying. I needed an extension cord for a venue with awkwardly placed outlets. The toggle switches for voltage selection are not recessed, which theoretically allows accidental changes during transport, though I never experienced this in practice.

9. Donner DP-1 – Entry-Level 10-Output Flexibility

The Donner DP-1 has been a gateway drug for thousands of guitarists moving from batteries and wall warts to organized pedalboard power. While not truly isolated in the transformer sense, the circuit-simulated isolation delivers respectable noise performance at a fraction of boutique prices. I used one for two years of regular gigging before upgrading.

Ten outputs provide impressive flexibility for the price point. Seven standard 9V ports handle normal pedals, while dedicated 12V and 18V outputs cover boutique effects. The single high-current 500mA output is essential for modern digital pedals. I powered a full board including a digital delay and multi-effects unit without issues.

The blue LED indicators are genuinely useful for dark stages. I could see at a glance if power was flowing to each pedal, which helped diagnose a bad cable during a gig once. The aluminum case feels more premium than the price suggests, and the compact size fits under most pedalboards without drama.

The noise performance is good but not exceptional. In venues with clean power, I never had issues. In places with fluorescent lights or dimmer switches, some hum crept in that true isolation would have eliminated. For the price, this is an acceptable compromise.

Who should buy the Donner DP-1

New pedalboard builders on a tight budget will find the DP-1 a massive upgrade from daisy chains and multiple wall warts. The ten outputs accommodate growth, and the voltage variety covers most common pedal requirements. If you are building your first board and cannot spend $150+ on power, this gets you started right.

Bedroom players and casual gigging musicians benefit from the LED indicators and reliable basic performance. The circuit simulation isolation is sufficient for most home and small venue situations. Consider this a stepping stone; when you are ready for true isolation, you will have a better sense of your actual power needs.

Who should skip the Donner DP-1

Professional recording engineers and tone purists will hear the difference between circuit simulation and true isolation. The noise floor is higher than transformer-isolated supplies, which matters in studio situations. If you are tracking through sensitive microphones, the cleaner power of a premium supply is worth the investment.

The 100mA standard outputs limit flexibility for modern digital pedals. Many contemporary reverbs, delays, and multi-effects need 200-300mA minimum. The single 500mA output helps, but large digital boards may find the current distribution limiting. Plan your pedal power requirements before purchasing.

10. Caline CP-209 – Mini True Isolation with Modern Features

The Caline CP-209 proves that true transformer-based isolation is becoming accessible at lower price points. I was skeptical about genuine isolation in a sub-$50 unit, but the separate transformers per output deliver clean power without the crosstalk that plagues budget supplies. For small boards needing quality power, this is a hidden gem.

Four outputs at 500mA each provide ample current for most pedals. Unlike many budget supplies with 100mA standard outputs, the Caline gives you high-current capacity on every port. This means you can run digital pedals without worrying about which output you plug into. The consistency is refreshing at this price point.

The Type-C output is a thoughtful addition for modern musicians. I use it to keep my wireless in-ear monitor pack charged between sets, and it doubles as a phone charger during breaks. The included mounting straps and daisy chain cable provide flexibility for different board layouts.

The aluminum construction feels surprisingly solid for the weight. At just 3.52 ounces, this is perfect for travel boards and fly dates. The short circuit protection on each output provides peace of mind when setting up quickly in unfamiliar venues.

Who should buy the Caline CP-209

Players with small boards of four or fewer pedals who want true isolation without the premium price will love the CP-209. The high-current outputs handle modern digital effects that many budget supplies struggle with. If you are building a compact travel board or need a backup power supply, this delivers surprising quality.

Tech-forward musicians appreciate the Type-C port. Keeping wireless systems, phones, and tablets charged from your pedalboard power is genuinely useful. The truly isolated outputs mean your tone stays clean even when charging devices simultaneously.

Who should skip the Caline CP-209

Four outputs is the absolute limit, with no expansion options. Players with growing pedal collections will outgrow this quickly. The short power cable also limits placement flexibility; if your board layout requires the power brick to be far from the supply, you may need an extension.

The thickness may be problematic for some low-profile pedalboards. At 1.38 inches, it is not the slimmest option available. Measure your board clearance before purchasing to avoid fitment issues. Players with slanted wooden boards should verify the height compatibility.

11. STRICH SPS-20 – Versatile Power with AC Outlets

The STRICH SPS-20 takes a different approach by combining pedal power with utility AC outlets. The four AC sockets provide 600W of capacity for amplifiers, keyboard power bricks, or other stage gear. For musicians who need an all-in-one power solution rather than just pedal power, this versatility is compelling.

Ten DC outputs provide adequate flexibility for most boards. The two 500mA ports handle higher-draw pedals, while the standard 100mA outputs cover analog effects. I appreciate the independent power control technology that isolates outputs from each other, though this is circuit-based rather than transformer isolation.

The compact 8 x 3-inch footprint fits comfortably under most pedalboards. The blue LED indicators provide clear status visibility on dark stages. The included cables and connectors cover standard connection needs without requiring additional purchases.

The noise performance is good for the price point, though not silent like true isolation. I noticed some high-pitched digital whine when pairing certain digital pedals with high-gain drives. Careful pedal grouping solves this, but it is a limitation compared to transformer-isolated supplies.

Who should buy the STRICH SPS-20

Musicians who need a central power hub for both pedals and other gear will find the AC outlets genuinely useful. Running a small amp, pedalboard, and perhaps a keyboard from one unit simplifies stage setup. If you play venues with limited outlets, the consolidated power solution is convenient.

Players upgrading from daisy chains who want more outputs and organization without the premium price of full isolation will appreciate the SPS-20. The ten DC outputs accommodate growing boards, and the AC sockets provide flexibility for other equipment. Consider this an organizational upgrade rather than a noise-elimination solution.

Who should skip the STRICH SPS-20

Purists seeking absolute silence should look at true isolated supplies. The circuit-based isolation works for many situations but cannot match transformer-based designs for noise elimination. High-gain players and recording musicians will hear the difference in noise floor.

The plastic enclosure raises durability concerns for heavy gigging. While fine for home and casual use, road warriors may want the confidence of an all-metal construction. The short power cable is another practical limitation for certain stage layouts.

12. JOYO DC 9V – Ultra-Budget Starter Power

The JOYO DC 9V represents the absolute entry point into organized pedal power. For less than the cost of a decent overdrive pedal, you get a reliable power supply that handles four effects simultaneously. I keep one as a backup in my gig bag and have used it for impromptu jams when my main board was unavailable.

The included four-way daisy chain is the star of the show. The cables are a practical length for standard pedalboard layouts, and the connectors fit securely into standard 9V pedals. The smart IC chip provides basic noise reduction and protection against overcurrent situations. This is not isolated power, but it is significantly better than using random wall warts.

The universal 100-240V input means this works anywhere in the world with a plug adapter. At 113 grams, it adds negligible weight to your gig bag. The CE, FCC, and RoHS certifications provide confidence in basic safety standards, which is not guaranteed at this price point.

I have powered tuners, overdrives, choruses, and delays from this supply without catastrophic noise issues. In clean power environments, it performs adequately. The limitations become apparent in venues with fluorescent lights or dimmer circuits, where true isolation would eliminate the hum that this unit passes through.

Who should buy the JOYO DC 9V

Absolute beginners with three to four pedals who cannot justify spending $100+ on power should start here. The JOYO gets you gigging reliably without the complexity of larger supplies. If you are not sure whether pedalboarding is for you long-term, this minimal investment lets you experiment.

Backup and emergency power needs justify keeping one of these around. I have loaned mine to bandmates when their supplies failed, and it has saved gig nights. The light weight and small size make it perfect for travel kits and secondary practice setups.

Who should skip the JOYO DC 9V

Anyone with more than four pedals will find the daisy chain limiting. The lack of individual output control means you cannot selectively power pedals or handle different voltages. Players with mixed 9V/12V/18V pedals need a more sophisticated solution.

Recording musicians and tone purists will find the noise floor unacceptable for studio work. The non-isolated design means ground loops and AC interference affect your signal chain. Consider this a temporary solution while you save for a proper isolated supply rather than a long-term pedalboard component.

How to Choose the Right Pedalboard Power Supply

Selecting the best pedalboard power supply requires understanding your current needs and anticipating future growth. I have made expensive mistakes by buying too small and then upgrading six months later. Here is what I have learned about making the right choice the first time.

Understanding Isolated vs Non-Isolated Power

Isolated power supplies use transformers or switching circuits to separate each output electrically. This prevents ground loops and eliminates the hum that occurs when multiple pedals share a common ground. Non-isolated supplies, including basic daisy chains, connect all pedals to the same ground reference, which invites noise into your signal chain.

The difference is audible immediately when you A/B test them. A good isolated supply sounds like your guitar plugged directly into the amp. A daisy chain adds a subtle but annoying layer of hash and buzz, especially with high-gain pedals or in venues with fluorescent lighting. For must-have guitar pedals that shape your core tone, isolation preserves their character.

Calculating Your Power Requirements

Every pedal has a current draw rating measured in milliamps (mA). Most analog pedals draw less than 20mA, while digital pedals can require 200-400mA or more. Add up the current requirements for all your pedals, then add 20% headroom for safety and future additions.

Voltage is equally important. Standard guitar pedals use 9V DC center-negative power. Some boutique pedals require 12V or 18V for additional headroom. Check the specifications for each pedal on your board and ensure your power supply can deliver the required voltages. The adjustable outputs on supplies like the Truetone CS7 and LEKATO provide flexibility for mixed-voltage boards.

Planning for Pedalboard Growth

Always buy more outputs than you currently need. I started with a five-output supply for four pedals, thinking I was covered. Within a year, I had seven pedals and needed to upgrade. The cost difference between a five-output and ten-output supply is usually less than buying twice.

Expandability features like the Strymon Zuma’s 24V bus let you add more outputs later without replacing the entire supply. This future-proofs your investment as your tonal needs evolve. Consider where your board might be in two years, not just where it is today.

Physical Size and Mounting Considerations

Measure your pedalboard’s underside clearance before purchasing. Some supplies like the Truetone CS6 are specifically designed for low-profile boards, while bulkier units may require risers or top-mounting. The power cable exit location also affects mounting; side-exiting cables limit positioning options compared to end-exiting designs.

Consider your gigging reality. If you fly to gigs regularly, weight matters more than a local player driving to venues. The Caline CP-209 and MXR Mini Iso-Brick excel for travel situations, while heavier supplies like the Strymon Zuma provide more features at the cost of portability.
