Voodoo Lab Pedal Power ISO-5 Isolated Power Supply

At first my guitar was picking up noise from the MONDO. Please note that it was definitely the guitar and not something else in the signal path. After reorganizing my pedal board and repositioning the MONDO the problem went away. Testing again by laying the guitar directly on top of the MONDO resulted in the guitar picking up a lot of hum/noise from the MONDO. The same was true with a Donner ISO8. I think all of these pedal power supplies that have the transformer built-in emit electromagnetic interference and noise in the air around them. But they DO NOT introduce any noise into the guitar signal path, and actually do a very good job or providing clean power to the guitar pedals. This MONDO is a really nice unit and very well made.

I use two of these on one pedal board and another one for my small pedal board. I am very happy with them. I also like that they have a power outlet on the back for daisy-chaining them together.

This power supply is not cheap and will run you as much as an expensive effect pedal. That said I tried the cheap route and bought a couple Otraki Power Supplies which turned out to be a disaster. They were so noisy and my pedals emitted a lot of noise when engaged. I had to use a noise gate pedal to suppress it and make the setup usable. I finally decided to return them and invest in the Mondo. The difference is night and day. This thing is dead silent and I can use this one supply for all my pedals going to the preamp stage. I have a separate supply for my FX loop pedals.It is so versatile. You even have a couple outputs with a power sag feature. I wish the cables were a little longer but they work just fine. I Just have to be careful when moving my board around. This thing is too big to mount so having a little extra length would have been nice. I tested plugging my guitar directly into the amp versus running it through the board and the amp floor noise was the same. If you are going to invest in a pedal board array versus a multi effects board then you have to invest in A. A high quality power supply and B. High quality cables. As I have read, a pedal board is only as good as it's weakest link.

Absolutely stunning difference using this power supply in my pedal board. My bands sound guy was going crazy before I had this. He has to run noise gates on my channel just to calm the buzz and it was totally affecting my overall tone and more importantly my sustain. When I got this voodoo supply I reworked everything in my board and was blown away! I couldn’t wait for the gig that Friday to tell our engineer, “remove all of the noise gates on the board; they are no longer needed”. Obviously he was skeptical but during our sound check, he disabled the gates and was floored. Nothing, zip, zilch. No noise AT ALL! He cane over to me and asked what I had done to fix this and I told him about this isolated supply. Needless to say, he went and bought one that next week for his rig (he’s a guitarist as well). I can not recommend this highly enough. If ou have any unwanted noise in your rig, please give this a go. I promise you will not be disappointed.

honestly awesome power supply. my guitarists use these so i figured i'd get the same thing. happy with it. the cables it comes with are fine, but one of them already gave me an issue and needed replacement

In the life of every electric guitarist, pedals start to become important to your sound. Batteries provide the cleanest power but are expensive and plagued by the fact that we never can remember to unplug the cable. Dooh! The voodoo Pedal Power 2 Plus is a fine isolated power supply. I tested on my pedal board and found it only added 2-3 more dB to my ambient guitar signal (ambient as tested was 43-44dB which increased to 45-46dB). Not bad at all. Since I'm also an electrical engineer with time and parts to spare, I built a 3 channel isolated power supply out of an old PC ATC power supply (which uses a switching power supply rather than the voodoo linear power supply). I put in about $20 of parts I got on Ebay, and was able to build a supply that I'm happy with, and performed very similar to the voodoo. I could not make a distinction audibly, but when I tested it with my dB meter, it did add about 6-7dB above ambient (ambient was the same as above and sound increased to about 51-53). I'm not surprised it did worse given the underlying supply is switching type, which inherently are noisier. So a little worse than voodoo, but like I said that 6-7dB difference was hardly noticeable in the room, and for 20 bucks and a little bit of solder, I'm pretty happy with the results!The reason I'm giving 4 stars and not 5 are the following:-Current limits are absolutely appalling low 100mA, except for 5-6 which can go to 250mA. As more fancy Line6 and other pedals that demand more power come into to play, you'll find yourself tapped out quick and needing the more expensive Pedal Power DIGITAL model. My RC30 looper pedal needs almost 200mA, so even that is borderline. For comparison, my 3 isolated power channels can do 1-2amps (I have it fused to 2amp) per channel thanks to nice heat sinks and a robust fan. The size of mine is not much bigger than the pedal power 2.-What's with the short cables? 18" is not enough for most pedal boards even if you put the the supply in the center (and I don't want to do that). I ended up making my own cables. Perhaps if you have the kind that goes under the board you're ok, but I don't have one like that and neither do other people. Voodoo labs does carry longer cables (24" and 36") on their website. There are not decent quality right angle plugs sold anywhere(at least I haven't found them). Otherwise I would make my own cables.-Only 6 right angle cables? Who even uses the straights anymore? With the cost of pedal board space so high, it makes no sense. More cables please!-It really would benefit from a power switch in my opinion. I guess people put this in a place that can't be reached? But still. A switch would be nice.-Pricey. Look, I know you have to pay to get good stuff, but this this too much. A lot of other good isolated supplies out there are being made and not nearly this much. Probably is 40 overpriced.Pros:-Yes, there are alot of good things about this that people have already comment on. Clean power, helps cut down hiss, reliable, works well with pedaltrain (if you have one...). All true, so I won't dwell on what's already been mentioned.-Fantastic customer service! I sent an email asking a question and they gave me a call a few hours later. They listened carefully to my problem and found me a satisfactory solution very quickly. The representative was very courteous and had excellent customer service skills. I was very impressed!4 stars. Good but pricey, poorly thought out cables
