I've looked at a lot of the popular power supplies on the market like some of the voodoo labs and Truetone 1spot bricks and this one seemed to have the right amount of outputs for the price. I'm surprised that these don't seem to be more popular. I had some noise before I bought this and now everything is quite and absolutely no noise (still a little pickup hum, but my noise gate squashes that completely; no power noise at all). The LEDs are very bright but I guess that is better than not bright enough. I have a Pedaltrain Pro and the cables were long enough that I was able to string my Time Machine nearly all the way to the opposite corner of the board. I was a little concerned about the "sag" outputs but it seems that you can just set them to 9V and they act as a normal 9V output. Also another huge point that I didn't really see anyone talking about on the internet: it seems to power the Digitech Whammy 5 flawlessly. NOTE: this is the version 5 that is 9VDC from the factory (not the AC older versions). So the original Whammy power brick and input say 1300mA, but the Whammy manual says that it consumes <265mA. I think the adapter is a generic Harmon adapter for many things and so they just want you to use what they already make which happens to be 1300mA max. The pedal will only pull the required amperage from the brick at 9V, which again is <265mA and I'm pretty confident that value is accurate, otherwise it wouldn't be in the manual. To be safe I put it on the 450mA output and it works great!

Ho acquistato l’alimentatore in sostituzione di uno economico e sono spariti tutti i rumori di massa. Davvero ottimo

This is exactly what is advertised. It's one of the best power supplies out there. Buy it. True isolation and quiet.

Ich mag sehr gute Technik. Auch dann, wenn es darum geht, im Kulturbetrieb mitzumischen. Hier ist die Technik mehr als gut. Sie ist zuverlässig. Sie schaut super aus. Mit diesem Stromverteiler macht schon die Installation Spaß. Meine guten Effektgeräte fürs Gitarrespielen haben "guten Strom" verdient!
