Power supplies for pedals: 5 out 9V DC (120mA max each) isolated (it is the diffrence with the power supply cheaper) comes with several Cables (10, 25, 50cm) and to double of 18V and a garland with five outputs, so what food pedals 9.

I started feeding my pedalboard with a standard 9v power supply and a garland: the horror a buzz standard. So I bought a 9v power supply BOSS but it made no difference.
I am well informed and the conclusion to have a silent power supply with output indpendante and isolates to be of rsultat sr. The voodoo lab onreuse as I leaned over to the t-rex. And that happiness, not a breath ... Total silence!

One small snag, it is a little low amprage to power a multi-purpose zoom style B2 or G2. So 9 / 10.

So if you are looking for zero or zero hummm buzz for your pedals and effects without breaking the bank either (100), junior is the fuel tank you need.
