DP-1 Guitar Pedal Power Supply

This product works fantastic. Handles the 6 pedals I threw at it

This power source works great. It is so much less expensive than power sources at any major music equipment distributor. Donner makes great pedals I've never had an issue.

We were having noise issues with another power supply and we initially suspected that it was the pedal having a problem. However, once we swithed to the Donner power supply, all the noise went away. This power supply is highly recommended!

Update: As others have pointed out, this is clearly NOT a truly isolated power supply. As Mark says below, maybe "Individual outputs" would be better. That being said, I've been using it for about 11 months now and I've got to say, I like it a lot! It's never failed on my, is producing noise-free power, and has enough ports to handle pretty much everything on my board that doesn't have some special power need. Plus, the LED lights are so bright that I mounted it on my board so that they basically illuminate most of my pedals. So, your results might differ, but I've been very pleased. I'm keeping it at 4/5 stars because it is not truly isolated, as the company clearly implies, but I still think it is a good deal and well made. Original Post: I thought I'd try this out before dropping $$$ on a nicer power supply. At this price I figured it was cheap enough to risk it. I doubted that it could really have isolated plugs for this price, but I think it actually might! I'm no electronics wiz, but from the insides it does indeed look like the different plugs are separate from one another. I've not tried to test it out by purposely shorting anything, but so far it sounds good. I was previously powering a lot of my board with a Boss tuner with the daisy-chain power. That worked OK, but I did get some interference at times. I haven't been able to test my board out many places yet, but I do think it is quieter than it was. Directions have a load of stupid spelling and grammar errors (typical for cheap import), but I was actually impressed with the build quality. Honestly, when I opened it up I expected a daisy-chain of spliced wires inside. Looks a heck of a lot better than I expected! Overall, I think it is worth a try for folks who may not need a pro-level power supply but want something small and slick.

I just received my unit. It does not work. After some troubleshooting, determined that it is the power cord/adapter. The unit itself does work with a different power supply. However, the flow of current or electricity is not proper for some of the units because some are "ON" but don't work at all and one goes off after a few seconds. There's something very specific about the power distribution and this specific cord. I shouldn't have to research this and spend time/effort finding one when I've already purchased something for that purpose. I've contacted the company for a cord solution. Now we wait... 10/15/2024 UPDATE Donner Music (the company), ended up reaching out to me after I had sent them a note and followed the proper channels for product support. I had unfortunately already returned the item as it had been several days with no response. Long story short, they apologized for the delayed response, offered to help (if I still had it) and offered to send me a new unit to try out. The new one showed up a couple of days later. It worked just as expected. I've been able to plug in all the pedals I'm currently using for my rig, making the entire thing more efficient and "clean" which is what I wanted. Thank you DONNER MUSIC for stepping up and making things right. It is a "no brainer" type of product and so far, it works for me as intended. If you have multiple stomp-boxes, pedals, etc., to your instrument rig, I seriously recommend taking a look at one of these units and giving it a try. The LED lights give it a nice touch not just cosmetically (as it does look nice), but it gives some much-needed light when you're in a dark stage, studio room or other situation like that. I hope this helps those of you who are researching it or on the fence about getting one.

Good, simple power supply, small profile, I like it. My only issue is that it only came with one 1/8" connector and I need at least 2. Can't seem to find where to get that online, not sure what it's even called. Any ideas?

Works great only had it for a fews hours but so far i love it

Great power supply. I have them on three different pedal boards with no complaints.

good brand and quality

I was looking for a cheaper alternative to the stupidly expensive power supplies on the market. This one is works perfectly fine with my 8 pedals which are mounted on a pedaltrain JR. It's incredibly light and slots nicely either underneath the board or on top next to the other pedals. Great buy!

Have been using this power supply for a week. It has zero hum, very quiet. No issues, running 7 pedals in the 100ma connections.

Perfect power brick for my pedal board. No noise at all and gives excellent power to all my pedals. Can't recommend this model enough. I'm thinking of getting another one for my alternate setup. Highly recommended, good power source, and zero hum from the unit.

Bought it with high hope. But what a let down. The 12v does not work when i connected 4 9v pedals. If i only use the 12v, it works.
