Caline CP-205 Guitar Pedal Power Supply, DC 9V True Isolated Pedalboard Power Supply with 8 Totally Isolated Outputs(300mA/500mA), Noiselessly

I ordered this after going back and forth for quite awhile as to whether I needed an expensive power supply like Voodoo in order to get something that would work well. Had a bad experience with the Onstage unit, which claimed to be isolated, but with my simple 9 volt pedals was a mess of noise and one pedal didn't work at all. So, got nervous about trying another lower cost unit. But again, all I'm running are simple 9 volt <100 ma pedals. Did my research and decided to give this one a go, knowing I had free return. I was amazed to find it was whisper quiet, powering my 6 pedals with no issues at all. Also this unit is very small, so will easily fit underneath all but the lowest pedalboards. My only possible concerns are how rugged the unit itself and its power supply will prove to be. Only time will tell, but so far so good. Of course replacing the power supply would be an easy low cost fix if ever needed. If I did so I'd look for a power supply with a longer, heavier cord.

This power supply has been stable, quiet, and a good addition to my pedalboard. I was hesitant at first about the reliability and quality of this power supply since it was not a brand that I was familiar with. I took a chance and for the last several months, this power supply has powered 8 pedals without any glitches or hiccups. I've been pleasantly surprised. Because it has worked well, I went ahead and ordered a smaller Caline power supply for a 2nd pedalboard.

This power supply is completely isolated on both the ground (sleeve connector) and the -9-volt (center pin connector). This puts it in the same category as Voodoo Labs, Cioks, and Strymon products. While I have doubts about its build quality compared to those brands, it is priced at one-quarter of their cost. Previously, I purchased the "STRICH Totally True Isolated" power supply, and while the -9-volt connection was isolated, the ground was common across all the connectors. This setup resulted in a terrible high-pitched whine from my Tonex One. Now my pedal-board is totally silent. Thanks Caline!

Works as advertised. Nice option for spatially challenged pedal boards.

I didn’t know my amp could be so quiet with pedals!!! I was getting a high pitch noise from my delay pedal and slight hum with a sub $20 power supply. Decided to try this one and I’m glad I did. Seems to be made well and thin enough to fit under my Daddario pedal board.

This is my second power supply that I bought for my guitar board; the first one was for a bass board. Both supplies worked great for all my pedals and they have a small form factor that helps with mounting them under the boards. These supplies helped with the unwanted noise and tidier installation while providing plenty of power for my needs. Hopefully, they will last, fingers crossed.

surged and blew my strymon blue sky.

I bought it a few months ago, I have only powered 3 pedals so far on it, but it is working perfectly fine for them. I can't complain, it's a pedal powersupply, it IS isolated, and it works fine!

スタジオでのリハや曲作りアレンジには丁度良いかな！！ 勿論ライブでも。

I recently purchased this power supply and have to say it is everything that they claim it to be. All I can say with certainty is the supply produces no noise and quells those noisy pedals...perhaps attributed to fully isolated ports? At any rate, the power brick is solid. I run it on a mini board and it really does a nice job. The power adaptor cord is quite short and has to be extended. They could have afforded to make the cord longer. Other than that they unit seems solid and I have no complaints. For the price and the quality, it makes little sense to buy anything else.

Excelente fuente de poder, me gusto la calidad, en verdad es aislada y no mete nada de ruido, además de que es muy compacta. Justo las salidas que necesitaba. 10/10

This power supply solved a MAJOR 60 Hz noise issue I had a with a new high-gain drive pedal in my chain. I had tried using (3) different wall supplies from reputable vendors, but they didn't do the trick. It also cleaned up some of the noise I had coming out of a Univibe clone. Well worth the money. Be mindful of how you put in the jacks, though- by some fluke, I shorted out one of the little LEDS that show if the jack is in use. No big deal, the output still works. It's quite small and doesn't take up a lot of space. I should have bought one of these years ago.

Calidad muy buena para el bajo precio que tiene. Usa una de estas fuentes con un regulador de voltaje (o ya mínimo un multicontactos que sea supresor de picos) y no creo que tengas mayor problema.
