There are better ones from brands such as T-rex and Voodoo labs but for me now I'm using a cheaper alternative, the Belcat Power Station ($69).
Can power up to 8 9v + 2 selectable 6/9/12v outputs. Non isolated but I've got no problems with humming. I use it to power 5 pedals on my pedal board and everything works just fine.
I'm using a 1spot to power up 7 pedals. Some people have posted regarding some issues about a humming sound when used to power too many pedals - of which I have yet to experience.
VS 1 spot is a power adapter. It can be used with a daisy chain (preferably a VS 1 spot daisy chain) to power 5 or 8 pedals at a time. It is spotted at Blackwood.
I use it too, powering my wah, overdrive and synthesizer. Not too bad
hmm i just got one new dc supply.the biyang adapter..it is seriously damn good,no humming sound and stuff like that, and whats more its just 25$ with built in daisy chain ( able to power up 5 pedals)..i got it from standard value and their service is damn good..
