Voodoo Lab Pedal Power ISO-5 5-output Guitar Pedal Power Supply Reviews

Isolated Power Supply with 9V and 12V Outputs and a Dedicated 18V Output

Everyone knows the importance of clean power in the studio, but what about on the live stage? Of course you need clean power there. Imagine how bad a high-gain distortion pedal could sound if it were injected with a healthy dose of noise? Luckily Voodoo Labs is here to solve that problem with the Pedal Power ISO-5. The perfect solution for compact pedalboards (or as a second power supply for massive pedal setups), the Pedal Power ISO-5 can power up to five pedals with isolated, filtered power. There's even an 18V output! You won't believe how quiet your pedal board can be when the Pedal Power ISO-5 is providing the juice!

Voodoo Lab ISO-5 power supply

By Sweetwater Customer from OR

As always this pedal board power supply is excellent, easy to affix to bottom of pedal board, works perfectly, zero noise issues, and totally isolated between pedals. Combined with proven reliability over time, I have 14 yr old unit's still working perfectly, I only use VooDoo Lab power supplies on my boards.LK retired EE and guitar/amp hobbyist with Studio.

Silent Power

By Crayton B. from Texas

Ended up finally upgrading to an isolated power supply due to the acquisition of the Shure GLXD16+, which requires 400 mA of power. I upgraded to this and it fits perfectly on my pedalboard. Perfect for my small board as I do not use many pedals.

ISO 5

By ASM

I have 3. Work great. IEC power cords, not cheap little ones. I bought the splitters to power more pedals and reduce the 18 volt output to 9.

Check your Specs!

By Chris from Ohio
Music Background: Lifelong musician

For what it is, this is a great quality product. But I think the lack of features and flexibility turn this into a no deal for me. The 18V spot should definitely be switchable - a waste of an output for the most of us who don't have 18V needs. Second flexibility issue is with the mA available to each output. It has a combo 9V/12V at 400mA which helps, but this all comes from the same source. You'll be splitting that up if you use both. Some of those other 9V outputs need higher mA ratings available. I have 4 pedals and only 2 will work with this brick. Pedals are all over the spectrum these days and power supplies need to keep up. This one does not IMO.

It just works...

By David W. from Atlanta
Music Background: +50 years playing, 20 publishing TQR.

We'll, it's the gold standard in power supplies... We were using a tethered One Spot and getting a lot of noise, certain pedals weren't getting along with one another so made the change. All is quiet now. We'll review it in the ToneQuest Report and ToneQuest.

Reliable and versatile

By Dave from North Carolina
Music Background: Semi-pro musician 30+ years

This is the second voodoo labs device that I've purchased along with a pedal train system. I've been using my first purchase about 4 years now and have never had a single issue. Easy install, reliable performance!

Before: bzzzzzzzzz. Now: [crickets]

By Michael W. from York, PA

This power source has taken my noisy board (previously daisy chained powered) and made it whisper quiet. You can’t even hear the pedals click on and off! I am powering an 18v danelectro Cool Cat and a Line 6 M5 along with 3 regular 9V pedals.

Super happy with this LIGHT (in weight) power source!

Great Device and Low Noise!

By Bren
Music Background: Bass

I've been experiencing random clicks and hisses on my amp with my EHX Battalion Preamp+DI, this solved the issue. I only have a tuner and EHX preamp pedal for now and I'm looking forward to add a Sansamp, a separate compressor, and a Darkglass. This power supply is enough for most people like me who just wants a simple tone control setup. The power is very clean and quality is great. I'm giving is a 4 star because the 18V output shoul've switcheable, but great power supply nonetheless.

Great customer service

By Jay
Music Background: Semi pro

I was using an American 110V version in Europe with a step down volatage converter. The unit blew maybe because I had a 110 extension cord after the converter? Anyway, I called up Voodoo and they were super nice, had me send the unit in to the US repair facility and they repaired it and sent it back with no charge. Great customer service for something that might have been my fault to begin with. I've tried other low cost solutions for pedal power and nothing beats a power supply with isolated transformers. I do wish it had a voltage switch, though.

OUCH

By Blake
Music Background: Guitarist

I wont buy anything power management related from Voodoo Labs anymore. I got electrocuted last night by the 18v DC side of my ISO5 and it somehow skipped the downstepping for the voltage and hit me so hard my ears were ringing as what I imagine was a 110 converted to DC then not downstepped to 18v. I've only had it for less than a year and its on a surge protector not directly in the wall... so it managed to break somewhere internally and not failsafe stop before discharging at me.... I'll never own one again. Do yourself a favor and buy the Cioks they never electrocute their customers.

Sincerely,

Thankfully Not Fried Like A Chicken

Does What It Says!

By Trey C. from Jacksonville, FL

Really not much to say here. I only have 4 pedals so I didn't need a whole lot of power, but II can't stand 9V batteries, and who wants to have to plug in 4 wall warts every time they change locations. With this I only have 1 thing to plug in and all the 9V outputs have isolated power sections so I don't need to worry about any humming due to power. This is the cheapest option on the market for what I was looking for and it does exactly what I need it to do. Also has high amperage outputs for 9V and 12V (these output power sections are not isolated so keep that in mind). And also has an 18V output in case I need it at any point. All in all happy with my purchase!

Good things come in small packages

By Nate from Illinois
Music Background: 15 year guitarist

I've owned multiple Voodoo Labs PP2+ but never used half the outputs. This is a perfect fit for my small board with room to grow.

King of Tone 18v > Comprosser 12v > Aqua Puss 9v > Tuner 9v > Mesa DC2

Dead silent. The super clean power substantially lowered the amount of RFI in my signal chain.

Amazingly fast order processing and shipping. Placed the order about 3pm on Friday afternoon CST, was on my doorstep Monday at 2pm with free shipping.

Silence is golden!

By Bruce from Ft. Worth
Music Background: Intermediate guitarist

As advertised, this provides an excellent power source. I have a sensitive OD and needed an isolated power source and a looper that required at least 100mamps. It provided both. Also fitted nice and neatly under my pedal board.

The bag is excellent quality as well. Overall- an excellent product at an excellent price.

ISO-5 power supply

By Jester from Deset

Love the voodoo lab pedal power supplies. I have used them for years and never had any trouble with them. I needed a smaller one so I opted for this one. Perfect for my needs--small footprint and does its job. Would recommend to anyone.

Works great

By Adam A. from Johnstown, PA
Music Background: Performance Musician/Strings

I'm currently using it to power a DigiTech Drop, Maxon OD808, MXR Custom Comp and an ISP Decimator 2. It works fantastic. Isolated power is definitely the way to go for your pedal board.

A Proper Power Supply

By Sweetwater Customer
Music Background: Always learning intermediate old timer

Nicely executed product. Like the detachable power cord, and power light indicator. Overall quality and feel excellent.
Not 5 stars because one of the supplied pedal cords did not work. (The one that is red for use on the 12 or 18 volt option port).
I learned that some of the older Boss pedals (pre '95 I believe) will not work with the 9v port. So I used the 12v port. Thanks Voodoo for offering that option!
Finally I enjoy knowing that any hum or buzz is NOT originating from my previously used daisy chain budget power supply. And my pedal board looks more professional.
Sweetwater customer service is a definite 5 stars.
Enjoy!

AMAZING!!

By Wayne from Massachusetts

I had been dealing with ambient noise issues for months and it was driving me crazy. Went through all my pedal cables and guitar cables and replaced them with Mogami cables,.... still had noise! Finally broke down and bought the Voodoo Lab Power ISO-5 to replace the CHEAP Gator power supply that came with my Gator pedal board. INSTANT SILENCE!!!! Was totally blown away! Will never buy anything but Voodoo Lab from now on.

Awesome

By Larvey from Plant City,Fl
Music Background: Garage band gearhead

Does exactly what it claims to do. Isolation quieted my rig down. Now I can run 2 ODs without a noisegate. Very compact too. The 18v output came in handy with pigtronics class A boost. This thing really delivers what is says it will. Enough said. Get one and you won't be disappointed.

Best Power

By Dino G. from East Jordan, Mi

I have 2 pedal boards, each is powered by Pedal Power units. These are the only power supply I will use . all others fall short. buy this one.

Very Nice

By J. A. from Mission Viejo, California
Music Background: Hobbyist

It does exactly what I expected. It is quiet, stays cool and runs up to five pedals noise free. I recommend this to anyone looking for a real isolated regulated five output power supply for their effects. I've even used it with an old wah which generates some noise from the pedal itself. I now can hear what my pedals really sound like and which of them generate electrical noises. I wish I would have gotten it sooner.

Quiet power supply

By Roger from Greenville, Indiana
Music Background: Playing since 1979

This is an excellent, quiet power supply you'll love. I've been somewhat of an effects minimalist for years, relying only on an amp for reverb, distortion and maybe some chorus. I'd had an MXR Phase 90 for solos, since the late 80's, like any respectable Eddie Van Halen wannabe, but here I am, 47, and wanting to beef-up my sound.

I had used the Phase 90 and a 9 volt battery, never seemed to run out before I got tired of it. So when I got an MXR Carbon Copy analog delay and an MXR Analog Chorus (also on Eddie Van Valen's current pedalboard, btw), I was a little dismayed when I started eating a 9 volt each per day. These were Energizers, no less. I was planning on getting an MXR EVH flanger, which takes two 9 volt batteries, and I could already see myself buying three packs of batteries a week. Buying a power supply and not buying batteries was a no brainer. And removing and screwing back in 4 screws from the back of each MXR pedal to replace a battery, every day, is a drag.

You look at the prices of a power supply like this and say to yourself, "a little pricey. Why can't they be as cheap as a power strip at Walmart?" Do some research like I did. Unlike a power strip, these magic boxes isolate the current, for each pedal, so you don't get unwanted crossover noise. And on this ISO 5, you get different voltage levels for the mere mortal 9 volt pedals, and the larger ones, like my 18 volt flanger.

So look at your pedal lineup and see if this unit has enough lines. I only run one 18-volt and three 9-volt pedals, so this is perfect for me. It's quiet, like it should be. I could have bought a larger power supply, but figure I can always just add another ISO 5 and place it on the board if I need it.

Again, the Voodoo Labs ISO 5 power supply is great, you won't regret buying it. And you certainly won't regret getting it at Sweetwater as they have incredibly fast shipping.

Great little power supply

By Max M. from Duvall, WA

I love this power supply! It is nice. Not the sexiest thing in the world, but again its just a power supply. I'm not a pro, but I can tell you I really enjoy it and am very happy with it. It works for all my pedals. Still trying to figure out what I want for that 18v spot...maybe a carbon copy. As usual Sweetwater's service is amazing.

Cleaned up the noise.

By Sweetwater Customer from Wisconsin's East Coast
Music Background: Guitar Guy

I was getting all kinds of nasty noise from my pedals when using the built in power supply on my pedal board. A friend highly recommended using a VooDoo lab power supply. I bought the ISO 5 to power my tuner, Boss DS1, a Digitech Delay and a Digitech Chorus. Now I have nothing but pure quiet signal.

Voodo Lab Pedal Power

The pedal power unit works great! It eliminates a mess of power sources and chords. It makes for a neat, functional pedal board.

May 27, 2014

Good Device

By Ben S. from United States
Music Background: Semi-Pro

This power supply is running fine, no hum problem. It is necessary to understand that there is a total of 4 9v outlets and that if you are running one effect using the 12v outlet then you are down to 3 9v outlets since one outlet is either/or 9v/12v. This unit did not solve a ground loop problem that was causing serious trouble in my setup, but that problem was resolved when I powered my BOSS TU-1 Floor Tuner directly from a wall outlet via a 9v adapter instead of powering it from the Power Supply.

Voodoo Lab pedal power ISO 5 (fantastic)

By Stephen (. from Kalona, Iowa USA

Why did I wait?

By Eric from Scottsdale, AZ
Music Background: Cover bands, hard rock, clubs and bars.

Why did I wait so long to buy this? I have tried using daisy chains for my pedals, mostly Boss, but have had bad luck with lot's of noise. I was getting really tired of changing 9 volt batteries all the time, so I decided to try one of these Voodoo Labs Power Supplies. Thing works great! No noise, easy to set up, and takes up hardly any room on my pedal board.

Clean Power

By Paul from Portland, ME USA
Music Background: Professional Musician

I mounted the ISO-5 to my Pedaltrain board. I run a Nova System and 4 other pedals. It's great to not have to worry about batteries or electrical noise/interference anymore. Way better than the wall wart style, daisy chain thingy I used to have. Move on up to the good stuff, you're worth it.

Great power supply

By John from Plymouth, NH
Music Background: working musician

Have two of these. One for my bass pedal board and one for my acoustic guitar pedal board. Quite, solid, reliable power. Only suggestion would be to have the 18v spot also double as 9v.

Great product

By Josh from USA
Music Background: More than just a hobby, but not professional. Bass Guitar

I've been using it to power multiple stomp boxes, including the 18V Mutron III+. No problems and a great alternative to a gaggle of wall warts. More expensive than the smaller Joyo, but it's fully isolated, and Voodoo Labs is high quality equipment.
My first time buying from Sweetwater...truly fantastic customer service. I've never gotten better help for an online purchase.

By eelcloud from Oakland,CA
Music Background: Recording Guitarist

Q-U-I-E-T!!!! Wish I'd had this 20 years ago-not sure how the engineers did it, but this is a pedalboards' first mate. Reliable, and did I mention the lack of noise? If you are used to hearing static hash from your pedal power system, and mentally filing it away under "oh well..."-
This is built for you. I don't know how they could've made this a better product-seems no details were spared. If you can't power super-suckers like Strymon or Eventide, Voodoo Lab makes a model that will suit your needs-try the Pedal Power Digital!
