Until now I've powered my pedals with batteries and 9v adapters, the adapters sometimes cause hum and the batteries are a pain in the a**, first because they die on you when you least expect and second, you have to unplug all your pedals so you don't drain the battery...
Now its all neat, connected and ready to play when ever I want.
The build quality is just great and the 12 isolated outputs are more than enough, in the price range and above it, it beats everything.
12v and 18v switch for the one output is a really great feature for those rare pedals that use it.
The power supply can be used all over the world since there is a 110-220v switch in the back.
It sure made my life much easier and it will make yours too, I bet on it.
